General 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 (CPAB or CPBA) goes HIGH. Output Enable (OEAB, OEBA) and Select (SAB, SBA) pins are provided for bus management.
