74F455 Octal Buffer/Driver with Parity, Inverting (3-State) 74F456 Octal Buffer/Driver with Parity, Non-Inverting (3-State)

FEATURES
· High impedance NPN base inputs for reduced loading
DESCRIPTION

The 74F455 and 74F456 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 7.5ns

· 74F456 combines 74F244 and 74F280A functions in one package· is a center pin version of the 74F656A· 74F456 Non-Inverting· 3-State outputs sink 64mA and source 15mA· 24-pin plastic Slim DIP (300 mil) package· Broadside pinout simplifies PC board layout
