LM339N Low Power Quad Voltage Comparator

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 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
