74F646 • 74F646B • 74F648 Octal Transceiver/Register with 3-STATE Outputs March 1988 Revised August 1999 74F646 • 74F646B • 74F648 Octal Transceiver/Register with 3-STATE Outputs 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.
In the transceiver mode, data present at the high impedance port may be stored in either the A...
