EL5281

Dual 8ns High-Speed Comparator

The EL5281 comparator is designed

for operation in single supply and dual

supply applications with 5V to 12V

operate from 0.1V below ground for use in ground-sensing

applications.

The output side of the comparator 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 EL5281 can be used to hold the

comparator output value by applying a low logic level to the

pin. The EL5281 features two separate comparators.

The EL5281 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 (EL5181) and

quad versions (EL5481 and EL5482).
