General Description
The EL5283C 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 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 EL5283C can be used to hold the comparator
output value by applying a low logic level to the pin.
The EL5283C contains two comparators set up as a window comparator. A single input is compared with a high and low reference. When
the output goes beyond one of these reference signals, the relevant output goes high.
The EL5283C in the 10-pin MSOP package and is specified for operation over the full -40°C to +85°C temperature range. Also available
are a single (EL5181C) and quad versions (EL5481C and EL5482C).
