LM393W datasheet



These 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.
All the pins are protected against electrostatic discharge up to 2 kV. As a consequence, the input voltages must not exceed the magnitude of VCC+ or VCC-.


1. Low input bias current : 25 nA typ

2. Low input offset current : ±5 nA typ

3. Low input offset voltage : ±1 mV typ

4. Input common-mode voltage range includes ground

5. Low output saturation voltage : 250 mV typ.
