Description

The EL5287C 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 EL5287C can be used to hold the comparator output value by applying a low logic level to the pin.
The EL5287C 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 EL5287C is available 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 (EL5185C) and quad versions (EL5485C and EL5486C.)
