Description
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.

■ Wide single-supply voltage range or dual supplies: +2V to +36V or ±1V to ±18V
■ Very low supply current (0.4mA) independent of supply voltage (1mW/comparator at +5V)
■ Low input bias current: 25nA typ.
■ Low input offset current: ±5nA typ.
■ Low input offset voltage: ±1mV typ.
■ Input common-mode voltage range includes ground
■ Low output saturation voltage: 250mV typ. (Io = 4mA)
■ Differential input voltage range equal to the supply voltage
■ TTL, DTL, ECL, MOS, CMOS compatible outputs
