LM393 - ST Microelectronics Function Overview

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.
Key Features
Wide single-supply voltage range or dual supplies: 2 V to 36 V or ±1 V to ±18 V
Very low supply current (0.45 mA) independent of supply voltage (1 mW/comparator at 5 V)
Low input bias current: 20 nA typ.
Low input offset current: ±3 nA typ.
Low input offset voltage: ±1 mV typ.
Input common-mode voltage range includes ground
Low output saturation voltage: 80 mV typ. (Isink  = 4 mA)
Differential input voltage range equal to the supply voltage
TTL, DTL, ECL, MOS, CMOS compatible outputs
Available in DFN8 2x2, MiniSO8, TSSOP8, and SO8 packages
