Description
The devices in this series consist of dual/quad
independent
single
or
dual
supply
voltage
comparators on a single monolithic substrate. The
common mode input voltage range includes
ground even when operated from a single supply,
and the low power supply current drain makes
these comparators suitable for battery operation.
These types were designed to directly interface
with TTL and CMOS, Current drain is independent
of the supply voltage. The outputs can be
connected to other open-collector outputs to
achieve wired-AND relationships.
The LM2903 is dual channel version available in
8-pin SOP package. The LM2901 is quad channel
version available in 14-pin SOP package. All
devices are specified for the temperature range of
–40°C to +125°C.
