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
ground
• 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
• Intended for use in aerospace and defense
applications:

superior resilience to harsh
environments (acceleration, EMI,
thermal, humidity)
− Extended screening capability on
request
− Single fabrication, assembly, and test
site
− Temperature range (-40 °C to 150 °C)
Applications
• Aerospace and defense
• Harsh environments
Description
This device consists of two independent low-
power voltage comparators 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.
