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.

FEATURES
• High impedance NPN base inputs for reduced loading (40µA in High and Low states)
• 74F456 combines 74F244 and 74F280A functions in one package
• 74F456 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
