The EL5485 and EL5486 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 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 EL5486 can be used to hold the comparator output value by applying a low logic level to the pin.

The EL5485 is available in the 16-pin SO (0.150") package and the EL5486 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 (EL5185), dual (EL5285), and window comparator (EL5287) versions.
