EL5181

8ns High-Speed Comparator

The EL5181 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 EL5181 can be used to hold the com-

parator output value by applying a low logic level to the pin.

The EL5181 is available in the 8-pin SO package and is

specified for operation over the full -40°C to +85°C tempera-

ture range. Also available are a dual (EL5281), a window

comparator (EL5283), and quad versions (EL5481 and

EL5482).
