74ABT16657DGGRG4

The 74ABT16652 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT16652 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, (nOEBA) 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.
FEATURES
• Independent registers for A and B buses
