OW POWER QUAD VOLTAGE COMPARATORS
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 inc lud es grou nd
! Low output saturation voltage : 250mV typ,（Io = 4mA）
! Differential input voltage range equal to the supply
voltage
! TTL, DTL, ECL, MOS, CMOS compatible output
