DESCRIPTION

The 74ABT652A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

The 74ABT652A transceiver/register consists of bus transceiver circuits with 3-State outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes High. Output Enable (OEAB, OEBA) and Select (SAB, SBA) pins are provided for bus management.
