Description

   The 74ABTH16652 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

   The 74ABTH16652 transceiver/register consists of two sets 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 (nOEAB, (nNEBA ) and Select (nSAB , nSBA ) pins are provided for bus management.

   Two options are available, 74ABT16652 which does not have the bus-hold feature and 74ABTH16652 which incorporates the bus-hold feature.
