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 Low Input Offset Current: 5.0 nA Low Input Offset Voltage: 2.0 mV (max) LM393A 5.0 mV (max) LM293/393 Input Common Mode Range to Ground Level 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 N SUFFIX PLASTIC PACKAGE CASE 626 8 1 D SUFFIX PLASTIC PACKAGE CASE 751 (SO-8) Representative Schematic Diagram (Diagram shown is for 1 comparator) PIN CONNECTIONS Output A 1 2 8 VCC + Input - Input Output Inputs A Gnd 3 4 - + 7 VCC Output B Inputs B - +5 6 R2 2.1 k Q3 F1 Device Q10 Q1 Q2 R1 4.6 k Q11 Q8 Q9 Q12 Q15 Q16 LM293D LM393D LM393AN,N LM2903D LM2903N LM2903VD LM2903VN R4 2.0 k Q4 Q5 Q6 Q14 (Top View) ORDERING INFORMATION Operating Temperature Range TA = -25 to +85C TA = 0 to +70C TA = -40 to +105C Package SO-8 SO-8 Plastic DIP SO-8 Plastic DIP SO-8 TA = -40 to +125C Plastic DIP Rev 2 (c) Motorola, Inc. 1998 MOTOROLA ANALOG IC DEVICE DATA 1 LM393, LM393A, LM293, LM2903, LM2903V MAXIMUM RATINGS Rating Power Supply Voltage Input Differential Voltage Range Input Common Mode Voltage Range Output Short Circuit-to-Ground Output Sink Current (Note 1) Power Dissipation @ TA = 25C Derate above 25C Operating Ambient Temperature Range LM293 LM393, 393A LM2903 LM2903V Maximum Operating Junction Temperature LM393, 393A, 2903, LM2903V LM293 Storage Temperature Range Symbol VCC VIDR VICR ISC ISink PD 1/RJA TA -25 to +85 0 to +70 -40 to +105 -40 to +125 TJ(max) 125 150 Tstg -65 to +150 C C Value +36 or 18 36 -0.3 to +36 Continuous 20 570 5.7 Unit Vdc Vdc Vdc mA mW mW/C C ELECTRICAL CHARACTERISTICS (VCC = 5.0 Vdc, Tlow TA Thigh,* unless otherwise noted.)

The maximum output current may be as high as 20 mA, independent of the magnitude of VCC, output short circuits to VCC can cause excessive heating and eventual destruction. 2. At output switch point, VO Vdc, RS = 0 with VCC from 5.0 Vdc to 30 Vdc, and over the full input common mode range (0 V to VCC = -1.5 V). 3. 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.

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 k 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.
