... The 74ABT16841A Bus interface latch is designed to provide extra data width for wider data/address paths of buses carrying parity. The 74ABT16841A consists of two sets of ten D-type latches with 3-State outputs. The flip-flops appear transparent to the data when Latch Enable (nLE) is HIGH. This allows asynchronous operation, as the output transition follows the data in transition ...
