LM393 datasheet



The LM193, LM293, and LM393 devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible.

These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.


1. Wide single-supply voltage range or dual supplies: 2 V to 36 V or ±1 V to ±18 V

2. Very low supply current (0.45 mA) independent of supply voltage (1 mW/comparator at 5 V)

3. Low input bias current : 20 nA typ.

4. Low input offset current : ±3 nA typ.

5. Low input offset voltage : ±1 mV typ.

6. Input common-mode voltage range includes ground

7. Low output saturation voltage: 80 mV typ.

8. Differential input voltage range equal to the supply voltage

9. TTL, DTL, ECL, MOS, CMOS compatible outputs
