The EL5181 comparator is designed
for operation in single supply and dual
supply applications with 5V to 12V
between VS+ and VS-. For single supplies, the inputs can
operate from 0.1V below ground for use in ground sensing
applications.
The output side of the comparator can be supplied from a
single supply of 2.7V to 5V. The rail-to-rail output swing
enables direct connection of the comparator to both CMOS
and TTL logic circuits.
The latch input of the EL5181 can be used to hold the comparator
output value by applying a low logic level to the pin.
The EL5181 is available in the 8-pin SO package and is
specified for operation over the full -40°C to +85°C temperature
range. Also available are a dual (EL5281), a window
comparator (EL5283), and quad versions (EL5481 and
EL5482).
