Description
The EL5281 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 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).
