Order this document by LM393/D The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range–to–ground level with single supply operation. Input offset voltage specifications as low as 2.0 mV make this device an excellent selection for many applications in consumer automotive, and industrial electronics. • Wide Single–Supply Range: 2.0 Vdc to 36 Vdc • • • • • • • • • SINGLE SUPPLY, LOW POWER DUAL COMPARATORS SEMICONDUCTOR TECHNICAL DATA Split–Supply Range: ±1.0 Vdc to ±18 Vdc Very Low Current Drain Independent of Supply Voltage: 0.4 mA Low Input Bias Current: 25 nA 8 Low Input Offset Current: 5.0 nA 1 Low Input Offset Voltage: 2.0 mV (max) LM393A 5.0 mV (max) LM293/393 Input Common Mode Range to Ground Level N SUFFIX PLASTIC PACKAGE CASE 626 Differential Input Voltage Range Equal to Power Supply Voltage Output Voltage Compatible with DTL, ECL, TTL, MOS, and CMOS Logic Levels ESD Clamps on the Inputs Increase the Ruggedness of the Device without Affecting Performance 8 1 D SUFFIX PLASTIC PACKAGE CASE 751 (SO–8) PIN CONNECTIONS Representative Schematic Diagram (Diagram shown is for 1 comparator) Output A VCC + Input – Input Output Inputs A 8 7 3 Gnd R2 2.1 k Q3 1 2 4 – + VCC Output B 6 – + 5 Inputs B (Top View) Q4 R4 Q5 Q6 Q14 2.0 k ORDERING INFORMATION F1 Device LM293D Q10 Q1 Q8 Q9 Q16 Q12 Q2 R1 4.6 k Q15 Q11 LM393D LM393AN,N LM2903D LM2903N Operating Temperature Range Package TA = –25° to +85°C SO–8 TA = 0° to +70°C TA = –40° to +105°C LM2903VD LM2903VN Plastic DIP SO–8 Plastic DIP SO–8 TA = –40° to +105°C Motorola, Inc. 1996 MOTOROLA ANALOG IC DEVICE DATA SO–8 Plastic DIP Rev 1 1 LM393, LM393A, LM293, LM2903, LM2903V MAXIMUM RATINGS Symbol Value Unit Power Supply Voltage Rating VCC +36 or ±18 Vdc Input Differential Voltage Range VIDR 36 Vdc Input Common Mode Voltage Range VICR –0.3 to +36 Vdc Output Short Circuit–to–Ground Output Sink Current (Note 1) ISC ISink Continuous 20 mA Power Dissipation @ TA = 25°C Derate above 25°C PD 1/RθJA 570 5.7 mW mW/°C Operating Ambient Temperature Range LM293 LM393, 393A LM2903 LM2903V Maximum Operating Junction Temperature LM393, 393A, 2903, LM2903V LM293 Storage Temperature Range °C TA –25 to +85 0 to +70 –40 to +105 –40 to +125 °C TJ(max) 125 150 Tstg °C –65 to +150 ELECTRICAL CHARACTERISTICS (VCC = 5.0 Vdc, Tlow ≤ TA ≤ Thigh,* unless otherwise noted.)

Due to the PNP transistor inputs, bias current will flow out of the inputs. This current is essentially constant, independent of the output state, there fore, no loading changes will exist on the input lines. 4. Input common mode of either input should not be permitted to go more than 0.3 V negative of ground or minus supply. The upper limit of common mode range is VCC –1.5 V. 5. Response time is specified with a 100 mV step and 5.0 mV of overdrive. With larger magnitudes of overdrive faster response times are obtainable. 6. The comparator will exhibit proper output state if one of the inputs becomes greater than VCC, the other input must remain within the common mode range. The low input state must not be less than –0.3 V of ground or minus supply. ] 2 MOTOROLA ANALOG IC DEVICE DATA LM393, LM393A, LM293, LM2903, LM2903V ELECTRICAL CHARACTERISTICS (VCC = 5.0 Vdc, Tlow ≤ TA ≤ Thigh,* unless otherwise noted.)

This gives the device oscillation tendencies if the outputs are capacitively coupled to the inputs via stray capacitance. This oscillation manifests itself during output transitions (VOL to VOH). To alleviate this situation, input resistors < 10 kΩ should be used. The addition of positive feedback (< 10 mV) is also recommended. It is good design practice to ground all unused pins. Differential input voltages may be larger than supply voltage without damaging the comparator’s inputs. Voltages more negative than –0.3 V should not be used. Figure 7.
