74F655A Octal buffer/driver with parity, inverting (3-State) 74F656A Octal buffer/driver with parity, non-inverting (3-State)

FEATURES

Significantly improved AC performance over 74F655 and 74F656 High impedance NPN base input for reduced loading

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

Ideal in applications where high output drive and light bus loading 74F655A combines 74F240 and 74F280A functions in one

74F655A Inverting 74F656A Non-inverting 3-State outputs sink 64mA and source 15mA 24-pin plastic Slim DIP (300mil) package Inputs on one side and outputs on the other side simplifies PC

Combined functions reduce part count and enhance system
