Window 4ns High-Speed Comparator

between V

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 EL5287 can be used to hold the

comparator output value by applying a low logic level to the

pin.

The EL5287 is a window comparator. A single input is

compared with a high reference and a low. When the output

goes beyond one of these reference signals, the relevant

output goes low.

The EL5287 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 (EL5185) and

quad versions (EL5485 and EL5486).
