EL5485, EL5486

Quad 4ns High Speed Comparators

The EL5485 and EL5486 comparators

are designed for operation in single

supply and dual supply applications

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 EL5486 can be used to hold the

comparator output value by applying a low logic level to the

pin.

The EL5485 is available in the 16-pin SO (0.150") package

and the EL5486 in the 24-pin QSOP package. Both are

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

temperature range. Also available are single (EL5185), dual

(EL5285), and window comparator (EL5287) versions.
