74ABT646 Octal Transceivers/Registers

The ABT646 consists 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 OE and direction pins are pro.
