74F646 Datasheet Octal Transceiver/Register

Manufacturer: Fairchild (now onsemi)

Overview: 74F646 • 74F646B • 74F648 Octal Transceiver/Register with 3-STATE Outputs March 1988 Revised August 1999 74F646 • 74F646B • 74F648 Octal Transceiver/Register with 3-STATE.

General Description

These devices consist of bus transceiver circuits with 3STATE, 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.

Control G and direction pins are provided to control the transceiver function.
