Overview

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. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to a High logic level.

  • 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
