General Description
The EL5287C 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 EL5287C can be used to hold the comparator
output value by applying a low logic level to the pin.
The EL5287C contains two comparators set up as a window compara-
tor. A single input is compared with a high and low reference. When
the output goes beyond one of these reference signals, the relevant out-
put goes high.
The EL5287C is available in the 10-pin MSOP package and is speci-
fied for operation over the full -40°C to +85°C temperature range.
Also available are a single (EL5185C) and quad versions (EL5485C
and EL5486C.)
