General Description

The EL5283C comparator is designed for operation in single supply

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 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 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 EL5283C in the 10-pin MSOP package and is specified for opera-

tion over the full -40°C to +85°C temperature range. Also available

are a single (EL5181C) and quad versions (EL5481C and EL5482C).
