These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance and input ruggedness through dedicated ESD clamps. The LM393B and LM2903B can drop-in replace the LM293, LM393 and LM2903, for both "A" and "V" grades. • • • • • NEW LM393B and LM2903B Improved specifications of B-version – Maximum rating: up to 38V – ESD rating (HBM): 2kV – Low input offset: 0.37mV – Low input bias current: 3.5nA – Low supply-current: 200µA per comparator – Faster response time of 1µsec – Extended temperature range for LM393B – Available in tiny 2 x 2mm WSON package B-version is drop-in replacement for LM293, LM393 and LM2903, A and V versions Common-mode input voltage range includes ground Differential input voltage range equal to maximumrated supply voltage: ±38 V Low output saturation voltage Output compatible with TTL, MOS, and CMOS Device Information PART NUMBER 2 Applications • • • • • • • • • • All devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Quiescent current is independent of the supply voltage.

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 can affect device reliability. Production Processing Does Not Necessarily Include Testing of All Parameters. All voltage values, except differential voltages, are with respect to network ground. Differential voltages are at IN+ with respect to IN–. Short circuits from outputs to VCC can cause excessive heating and eventual destruction. Input current flows thorough parasitic diode to ground and turns on parasitic transistors that increases ICC and can cause the output to be incorrect. Normal operation resumes when input current is removed.

This device has proven ubiquity and versatility across a wide range of applications. This is due to very wide supply voltages range, low Iq and fast response of the devices. The open-collector outputs allow the user to level shift to the desired logic level indpendent of VCC, while also enabling AND functionality when multiple outputs are connected together. 6.2 Functional Block Diagram VCC Internal Bias Q9 Q10 Q11 Q12 Q14 Itail D3 D2 Q2 Q3 Q15 Output D4 D1 VCM Clamp - Input Q1 I1 Q8 + Input I2 Q4 Q13 Q7 ESD Q6 Q5 ESD Figure 6-1. Schematic (Each Comparator) 6.3 Feature Description The comparator consists of a PNP Darlington pair input, allowing the device to operate with very high gain and fast response with minimal input bias current. The input Darlington pair creates a limit on the input common mode voltage capability, allowing the comparator to accurately function from ground to VCC– 2V over temperature. A clamp is added around Q3 to mimic the both inputs above input voltage range behavior of the original classic silicon. The output consists of an open drain NPN (pull-down or low side) transistor. The output NPN sinks current when the negative input voltage is higher than the positive input voltage and the offset voltage. The VOL is resistive and scales with the output current. Please see the "Output Low Voltage vs. Output Sinking Current" graphs for VOL values with respect to the output current. 6.4 Device Functional Modes 6.4.1 Voltage Comparison The device operates solely as a voltage comparator, comparing the differential voltage between the positive and negative pins and outputting a logic low or high impedance (logic high with pullup) based on the input differential polarity.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 7.1 Application Information The device is typically used to compare a single signal to a reference or two signals against each other. Many users take advantage of the open drain output to drive the comparison logic output to a logic voltage level to an MCU or logic device. The wide supply range and high voltage capability makes this comaprator an excellent choice for level shifting to a higher or lower voltage. 7.2 Typical Application VLOGIC VLOGIC VSUP Vin VSUP Rpullup + Vin+ ½ LM2903 Rpullup + ½ LM2903 Vin- Vref CL CL Figure 7-1.

If temperature operation is below 25°C the VICR can range from 0V to VCC– 2.0V.

Operation outside of this range can yield incorrect comparisons. The following is a list of input voltage situation and the outcomes: 1. When both IN- and IN+ are both within the common-mode range: a. If IN- is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking current b. If IN- is lower than IN+ and the offset voltage, the output is high impedance and the output transistor is not conducting 2. When IN- is higher than common-mode and IN+ is within common-mode, the output is low and the output transistor is sinking current 3. When IN+ is higher than common-mode and IN- is within common-mode, the output is high impedance and the output transistor is not conducting 4. When IN- and IN+ are both higher than common-mode, see Section 2 of Application Design Guidelines for LM339, LM393, TL331 Family Comparators Including the New B-versions. 7.2.2.2 Minimum Overdrive Voltage Overdrive Voltage is the differential voltage produced between the positive and negative inputs of the comparator over the offset voltage (VIO). To make an accurate comparison the Overdrive Voltage (VOD) must be higher than the input offset voltage (VIO). Overdrive voltage can also determine the response time of the comparator, with the response time decreasing with increasing overdrive. Figure 7-2 and Figure 7-3 show positive and negative response times with respect to overdrive voltage. 7.2.2.3 Output and Drive Current Output current is determined by the load/pull-up resistance and logic/pullup voltage. The output current produces a output low voltage (VOL) from the comparator. In which VOL is proportional to the output current. See the Output Low vs. Sinking Current graphs in the Typical Characteristics, LMx93x and LM2903x section to determine VOL based on the output current. The output current can also effect the transient response. See Section 7.2.2.4 for more information. 7.2.2.4 Response Time Response time is a function of input over drive. See Application Curves for typical response times. The rise and falls times can be determined by the load capacitance (CL), load/pullup resistance (RPULLUP) and equivalent collector-emitter resistance (RCE). • • The rise time (τR) is approximately τR = RPULLUP × CL The fall time (τF) is approximately τF = RCE × CL – RCE can be determine by taking the slope of Figure 5-20 in the linear region at the desired temperature, or by dividing the VOL by Iout Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback Product Folder Links: LM393B LM2903B LM193 LM293 LM293A LM393 LM393A LM2903 LM2903V 19 LM393B, LM2903B, LM193, LM293, LM293A, LM393, LM393A, LM2903, LM2903V www.ti.com SLCS005AH – OCTOBER 1979 – REVISED APRIL 2025 7.2.3 Application Curves 6 6 5 5 Output Voltage (Vo) Output Voltage, Vo(V) The following curves are generated with 5V on VCC and VLogic, RPULLUP = 5.1kΩ, and 50pF scope probe. 4 3 2 5mV OD
