GENERAL DESCRIPTION
This device consists of four independent precision voltage comparators with an offset voltage specification as low as 2mV max for CM339.   All these comparators were designed specifically to operate from a single power 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.

FEATURES
Wide single supply voltage range or dual supplies for all devices: +2V to +36V or ±1V to ±18V
Very low supply current（1.1mA）independent of supply voltage（1.4mW/comparator +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 output
