General description
The 74ABT648 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT648 transceiver/register consists of bus transceiver circuits with inverting 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.
