EL5281
Dual 8ns High-Speed Comparator
The EL5281 comparator is designed
for operation in single supply and dual
supply applications with 5V to 12V
between V
S
+ and V
S
-. For single supplies, the inputs can
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 EL5281 can be used to hold the
comparator output value by applying a low logic level to the
pin. The EL5281 features two separate comparators.
The EL5281 is available in the 14-pin SO package and is
specified for operation over the full -40°C to +85°C
temperature range. Also available are a single (EL5181) and
quad versions (EL5481 and EL5482).
