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. 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 may cause output to be incorrect. Normal operation resumes when input current is removed. 6.2 Recommended Operating Conditions Over operating free-air temperature range (unless otherwise noted) Supply voltage, VS = (V+) – (V–) Input voltage range, VIVR Ambient temperature, TA 4 Submit Document Feedback MIN MAX non-V devices 2 30 V devices 2 32 "B" version devices 2 36 non-B devices 0 (V+) – 2.0 "B" version devices –0.1 LM193 –55 125 LM2903, LM2903V, LM2903AV, LM2903B –40 125 LM393B –40 85 LM293, LM293A –25 85 LM393, LM393A 0 70 UNIT V V °C Copyright © 2020 Texas Instruments Incorporated Product Folder Links: LM393B LM2903B LM193 LM293 LM293A LM393 LM393A LM2903 LM2903V LM393B, LM2903B, LM193, LM293, LM293A, LM393, LM393A, LM2903, LM2903V www.ti.com SLCS005AE – OCTOBER 1979 – REVISED NOVEMBER 2020 6.3 Thermal Information: LM193 LM193 D (SOIC) THERMAL METRIC(1) UNIT 8 pin RθJA Junction-to-ambient thermal resistance 126.4 RθJC(top) Junction-to-case (top) thermal resistance °C/W 70 °C/W RθJB ψJT Junction-to-board thermal resistance 64.9 °C/W Junction-to-top characterization parameter 20.3 °C/W ψJB Junction-to-board characterization parameter 64.5 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance n/a °C/W (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics report. 6.4 Thermal Information: LM293, LM393, LM2903 (all 'V' and 'A' suffixes) LM293, LM393, LM2903 THERMAL METRIC(1) D (SOIC) DGK (VSSOP) P (PDIP) PS (SO) PW (TSSOP) UNIT 8 pin 8 pin 8 pin 8 pin 8 pin RθJA Junction-to-ambient thermal resistance 131.8 199.4 73.7 139 194.1 °C/W RθJC(top) Junction-to-case (top) thermal resistance 78.4 90.2 62.6 98.9 77.0 °C/W RθJB Junction-to-board thermal resistance 72.2 120.8 50.8 83.7 123.0 °C/W ψJT Junction-to-top characterization parameter 26.5 21.5 39.2 47.4 13.1 °C/W ψJB Junction-to-board characterization parameter 71.1 119.1 50.7 83 121.3 °C/W (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics report. 6.5 Thermal Information: LM393B and LM2903B LM393B, LM2903B THERMAL METRIC(1) D (SOIC) PW (TSSOP) DGK (VSSOP) DDF (SOT-23) DSG (WSON) 8 pins UNIT 8 pin 8 pin 8 pin 8 pin RθJA Junction-to-ambient thermal resistance 148.5 200.6 193.7 197.9 96.9 °C/W RθJC(top) Junction-to-case (top) thermal resistance 90.2 89.6 82.9 119.2 119.0 °C/W RθJB Junction-to-board thermal resistance 91.8 131.3 115.5 115.4 63.1 °C/W ψJT Junction-to-top characterization parameter 38.5 22.1 20.8 19.4 12.4 °C/W ψJB Junction-to-board characterization parameter 91.1 129.6 113.9 113.7 63.0 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance - - - - 37.8 °C/W (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics report. 6.6 ESD Ratings VALUE UNIT LM393B and LM2903B Only V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1000 Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±1000 Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±750 V All Other Versions V(ESD) (1) (2) Electrostatic discharge V JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

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-drain output allows the user to configure the output's logic high voltage (V OH) and can be used to enable the comparator to be used in AND functionality. 7.2 Functional Block Diagram VCC 80-µA Current Regulator 10 µA IN+ 60 µA 10 µA 80 µA COMPONENT COUNT OUT Epi-FET Diodes Resistors Transistors 1 2 2 30 IN− GND Figure 7-1. Schematic (Each Comparator) 7.3 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 V CC– 1.5 V input. Allow for VCC– 2 V at cold temperature. 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 V OL is resistive and scales with the output current. See Figure 6-3 for VOL values with respect to the output current. 7.4 Device Functional Modes 7.4.1 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. 18 Submit Document Feedback Copyright © 2020 Texas Instruments Incorporated Product Folder Links: LM393B LM2903B LM193 LM293 LM293A LM393 LM393A LM2903 LM2903V LM393B, LM2903B, LM193, LM293, LM293A, LM393, LM393A, LM2903, LM2903V www.ti.com SLCS005AE – OCTOBER 1979 – REVISED NOVEMBER 2020 8 Application and Implementation Note Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. 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. 8.1 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 optimal for level shifting to a higher or lower voltage. 8.2 Typical Application VLOGIC VLOGIC VSUP Vin VSUP Rpullup + Vin+ ½ LM2903 Rpullup + ½ LM2903 Vin- Vref CL CL Figure 8-1.

If temperature operation is below 25°C the V ICR can range from 0 V to VCC– 2.0 V. This limits the input voltage range to as high as V CC– 2.0 V and as low as 0 V. Operation outside of this range can yield incorrect comparisons.

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, the output is low and the output transistor is sinking current 8.2.2.2 Minimum Overdrive Voltage Overdrive Voltage is the differential voltage produced between the positive and negative inputs of the comparator over the offset voltage (V IO). To make an accurate comparison the Overdrive Voltage (V OD) should be higher than the input offset voltage (V IO). Overdrive voltage can also determine the response time of the comparator, with the response time decreasing with increasing overdrive. Figure 8-2 and Figure 8-3 show positive and negative response times with respect to overdrive voltage. 8.2.2.3 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 (V OL) from the comparator. In which V OL is proportional to the output current. Use Section 6.14 to determine VOL based on the output current. The output current can also effect the transient response. See Section 8.2.2.4 for more information. 8.2.2.4 Response Time Response time is a function of input over drive. See Section 8.2.3 for typical response times. The rise and falls times can be determined by the load capacitance (CL), load/pullup resistance (RPULLUP) and equivalent collectoremitter 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 Section 6.14 in its linear region at the desired temperature, or by dividing the VOL by Iout 8.2.3 Application Curves 6 6 5 5 Output Voltage (Vo) Output Voltage, Vo(V) The following curves were generated with 5 V on VCC and VLogic, RPULLUP = 5.1 kΩ, and 50 pF scope probe. 4 3 2 5mV OD 1 20mV OD 0 4 3 2 5mV OD 1 20mV OD 0 100mV OD ±1 -0.25 0.25 0.75 1.25 Time (usec) 1.75 2.25 C004 Figure 8-2.

This variation can eat into the input common-mode range of the comparator and create an inaccurate comparison. 10 Layout 10.1 Layout Guidelines For accurate comparator applications without hysteresis it is important maintain a stable power supply with minimized noise and glitches. To achieve this, it is best to add a bypass capacitor between the supply voltage and ground. This should be implemented on the positive power supply and negative supply (if available). If a negative supply is not being used, do not put a capacitor between the IC's GND pin and system ground. Minimize coupling between outputs and inverting inputs to prevent output oscillations. Do not run output and inverting input traces in parallel unless there is a V CC or GND trace between output and inverting input traces to reduce coupling. When series resistance is added to inputs, place resistor close to the device. 10.2 Layout Example Better Ground PF Input Resistors Close to device 1 1OUT 2 1IN- VCC 8 VCC 2OUT 7 OK VCC or GND Ground 3 1IN+ 2IN- 6 4 GND 2IN+ 5 Figure 10-1.
