74F649 - Octal transceiver/register

Description

The 74F647 and 74F649 Transceivers/Registers consist of bus transceiver circuits with open-collector outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers.

Features

  • 74F647/74F649.
  • High impedance NPN base inputs for reduced loading (20µA in High and Low states).
  • Independent registers for A and B buses.
  • Multiplexed real-time and stored data.
  • Choice of non-inverting and inverting data paths.
  • Open Collector outputs.
  • 300 mil wide 24-pin Slim Dip package.
