74F455 - Buffers/drivers

General 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.

Key Features

  • 74F455,.
  • 74F456.
  • High impedance NPN base inputs for reduced loading (40µA in High and Low states).
