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.

FEATURES
• Significantly improved AC performance over 74F655 and 74F656
• High impedance NPN base input for reduced loading (40µA in High and Low states)
• Ideal in applications where high output drive and light bus loading are required
     (IIL is 40µA vs. FAST std of 600µA)
• 74F655A combines 74F240 and 74F280A functions in one package
• 74F656A combines 74F244 and 74F280A functions in one package
• 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 board layout
• Combined functions reduce part count and enhance system performance
• Industrial temperature range available (–40°C to +85°C)
