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

Description
This device consists of two independent low-
power voltage comparators designed specifically
to operate from a single supply over a wide range
of voltages. Operation from split power supplies is
also possible.
The input common-mode voltage range includes
the negative rail even though operated from a
single power supply voltage.
All the pins are protected against electrostatic
discharge up to 2 kV. As a consequence, the input
voltages must not exceed the magnitude of V_CC+
or V_CC-.
