EL5481, EL5482

Quad 8ns High-Speed Comparators

DATASHEET

The EL5481 and EL5482 comparators are designed for

operation in single supply and dual supply applications with

5V to 12V between VS+ and VS-. For single supplies, 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 EL5482 can be used to hold the

comparator output value by applying a low logic level to the

pin.

The EL5481 is available in the 16-pin SO (0.150") package

and the EL5482 in the 24-pin QSOP package. All are

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

temperature range. Also available are a single (EL5181), a

dual (EL5281), and a window comparator (EL5283).
