General Description
The EL5285C 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 comparators can be supplied from a single sup-
ply 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 EL5285C can be used to hold the comparator
output value by applying a low logic level to the pin. The EL5285C
features two separate comparators
The EL5285C is available in the 14-pin SO package and is specified
for operation over the full -40°C to +85°C temperature range. Also
available are a single (EL5185C) and quad versions (EL5485C and
EL5486C.)
