74F655A Datasheet Octal Buffer/driver

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: INTEGRATED CIRCUITS 74F655A* Octal buffer/driver with parity, inverting (3-State) 74F656A Octal buffer/driver with parity, non-inverting (3-State) * Discontinued part. Please see the Discontinued Product List.

General Description

The 74F655A and 74F656A are octal buffers and line drivers with parity generation/checking designed to be employed as memory address drivers, clock drivers and bus-oriented transmitters/receivers.

These parts include parity generator/checker to improve PC board density.

TYPICAL PROPAGATION DELAY 6.5ns 6.5ns • Ideal in applications where high output drive and light bus loading • 74F655A bines 74F240 and 74F280A functions in one package are required (IIL is 40µA vs.
