74F646A - Octal transceiver/register

General Description

The 74F646/74F646A and 74F648/74F648A transceivers/registers consist of bus transceiver circuits with 3 state outputs, D type flip

flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers.

Key Features

  • Combines 74F245 and two 74F374 type functions in one chip.
  • High impedance base inputs for reduced loading (70µA in high and low states).
