General Description
The EL5485C and EL5486C comparators are 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 EL5485C and EL5486C can be used to hold the
comparator output value by applying a low logic level to the pin.
The EL5485C is available in the 16-pin SO package and the EL5486C
in the 24-pin QSOP package. Both are specified for operation over the
full -40°C to +85°C temperature range. Also available are single
(EL5185C), dual (EL5285C), and window comparator (EL5287C)
versions.
