Description

The 74ABTH16543 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

The 74ABT161543 16-bit registered transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate Latch Enable (nLEAB, nLEBA) and Output Enable (nOEAB, nOEBA) inputs are provided for each register to permit independent control of data transfer in either direction. Master reset (MR) clears all registers simultaneously and sets them Low.The outputs of the 74ABTH16543 are guaranteed to sink 64mA.
