Parallel-in access to each stage is provided by eight individual direct data (A−H) inputs that are enabled by a low level at the shift/load (SH/LD) input. The SNx4HC165 devices also feature a clock-inhibit (CLK INH) function and a complementary serial (QH) output. 1 Wide Operating Voltage Range of 2 V to 6 V Outputs Can Drive Up to 10 LSTTL Loads Low Power Consumption, 80-µA Maximum ICC Typical tpd = 13 ns ±4-mA Output Drive at 5 V Low Input Current of 1 µA Maximum Complementary Outputs Direct Overriding Load (Data) Inputs Gated Clock Inputs Parallel-to-Serial Data Conversion On Products Compliant to MIL-PRF-38535, All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters. Clocking is accomplished by a low-to-high transition of the clock (CLK) input while SH/LD is held high and CLK INH is held low. The functions of CLK and CLK INH are interchangeable. Because a low CLK and a low-to-high transition of CLK INH also accomplish clocking, CLK INH must be changed to the high level only while CLK is high. Parallel loading is inhibited when SH/LD is held high. While SH/LD is low, the parallel inputs to the register are enabled independently of the levels of the CLK, CLK INH, or serial (SER) inputs. 2 Applications • • • • • Device Information(1) Programable Logic Controllers Appliances Video Display Systems Output Expander Keyboards PART NUMBER PACKAGE BODY SIZE (NOM) SN74HC165D SOIC (16) 10.00 mm × 6.20 mm SN74HC165DB SSOP (16) 8.20 mm × 6.50 mm SN74HC165N PDIP (16) 6.60 mm × 18.92 mm SN74HC165NS SO (16) 8.20 mm × 9.90 mm SN74HC165PW TSSOP (16) 6.60 mm × 5.10 mm SN54HC165FK LCCC (20) 9.09 mm × 9.09 mm SN54HC165J CDIP (16) 21.34 mm × 7.52 mm SN54HC165W CFP (16) 9.40 mm × 7.75 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 6.2 ESD Ratings V(ESD) (1) Electrostatic discharge VALUE UNIT ±1500 V Human body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) VCC Supply voltage VIH High-level input voltage VIL Low level input voltage VI Input voltage VO Output voltage Δt/Δv (2) MIN NOM MAX 2 5 6 VCC = 2 V 1.5 VCC = 4.5 V 3.15 VCC = 6 V 4.2 VCC = 2 V 0.5 VCC = 4.5 V 1.35 VCC = 6 V 1.8 0 (1) (2) Operating free-air temperature V VCC V VCC V VCC = 2 V 1000 VCC = 4.5 V 500 VCC = 6 V TA V V 0 Input transition rise and fall time UNIT ns/V 400 SN54HC165 –55 125 SN74HC165 –40 125 °C All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. If this device is used in the threshold region (from VIL max = 0.5 V to VIH min = 1.5 V), there is a potential to go into the wrong state from induced grounding, causing double clocking. Operating with the inputs at tt = 1000 ns and VCC = 2 V does not damage the device; however, functionally, the CLK inputs are not ensured while in the shift, count, or toggle operating modes. 6.4 Thermal Information SN74HC165 THERMAL METRIC (1) RθJA (1) 4 Junction-to-ambient thermal resistance D (SOIC) DB (SSOP) N (DIP) NS (SO) PW (TSSOP) 73 82 67 64 108 UNIT °C/W For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953.

The device loads all the 8 bits simultaneously through parallel load input when SH/LD is low. This will also ignore any input at CLK or CLK INH. The device shifts the data when CLK toggles. The data is shifted on rising edge of the clock. Clock Inhibit (CLK INH) inhibits the clock function resulting in no change of the output. If SH/LD is low clock inputs are ignored. To realize the shift function, SH/LD should be high. CLK and CLK INH functions are interchangeable. If CLK is low then change a clock signal at CLK INH pin causes a shift of data to QH. If CLK INH is Low clock signal on CLK pin shifts the data out to QH. 8.2 Functional Block Diagram A SH/LD CLK INH CLK SER 1 B 11 C 12 D 13 E 14 F G 4 3 H 5 6 9 15 QH 2 S C1 1D R 10 S C1 1D R S C1 1D R S C1 1D R S C1 1D R S C1 1D R S C1 1D R S C1 1D R 7 QH Pin numbers shown are for theD, DB, J, N, NS, PW, and W packages.

It is typically tpd = 13 ns and has ±4-mA output drive at 5 V with low input current of 1-μA maximum. The device features the direct overloading load of data input, meaning parallel data is loaded irrespective of clock signals. 8.4 Device Functional Table Table 1 lists the functional modes of the SNx4HC165.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The SNx4HC165 is an 8-bit shift register that can be used as a serializer in order to reduce the number of connection needed when transmitting signals between boards or to the device. SNx4HC165 can be used to expand inputs for processors with limited GPIOs for examples basic keyboard interface to the controller. SNx4HC165 allows inputs to be load into the shift registers and clock is used to shift data to the processor. Multiple SNx4HC165 can be cascaded together to allow more digital inputs to be interfaced with single processor by connecting output of the cascaded shift register QH to serial input SER of the SNx4HC165 and so on. Note this application does not allow the communication to be bi-direction in nature as data can only be read by the processor not written back. 9.2 Typical Application 2 2 15 15 From other shift register 10 10 1 11 11 7 12 Digital Inputs / Keyboard 13 9 13 VCC 16 4 0.1µF 5 9 3 16 4 Controller, Processor 14 Data Data VCC 3 7 12 Digital Inputs / Keyboard 14 1 5 8 0.1 µF 8 6 6 Figure 5.

Propagation Delay vs Supply Voltage at TA = 25°C 10 Power Supply Recommendations The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Recommended Operating Conditions table. Each VCC pin must have a good bypass capacitor in order to prevent power disturbance. For devices with a single supply, a 0.1-μF capacitor is recommended and if there are multiple VCC pins then a 0.01-μF or 0.022-μF capacitor is recommended for each power pin. It is ok to parallel multiple bypass caps to reject different frequencies of noise. 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power pin as possible for best results. 11 Layout 11.1 Layout Guidelines Reflections and matching are closely related to loop antenna theory, but different enough to warrant their own discussion. When a PCB trace turns a corner at a 90° angle, a reflection can occur. This is primarily due to the change of width of the trace. At the apex of the turn, the trace width is increased to 1.414 times its width. This upsets the transmission line characteristics, especially the distributed capacitance and self–inductance of the trace — resulting in the reflection. It is a given that not all PCB traces can be straight, and so they will have to turn corners. Figure 7 shows progressively better techniques of rounding corners. Only the last example maintains constant trace width and minimizes reflections. 11.2 Layout Example BETTER BEST 2W WORST 1W min. W Figure 7.
