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


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


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
