74F456 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. One (1.0) FAST Unit Load (U.L.) is defined as 20µA in the High state and 0.6mA in the Low state.
