EL5181CS-T13

Manufacturer Part Number
EL5181CS-T13
Description
8ns High-Speed Comparator
Manufacturer
INTERSIL [Intersil Corporation]
Datasheet
8ns High-Speed Comparator
between V
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).
