This document is a description document for 74ABT16543 16-Bit Registered Transceiver with 3-STATE Outputs, which is produced by Fairchild Semiconductor Corporation.
The 74ABT16543 is a 16-bit transceiver containing two sets of D-type latches for temporary data storage with bidirectional data flow. It features separate control logic for each byte, allowing independent control of inputting and outputting in either direction. The device includes back-to-back registers and guarantees latchup protection with high impedance glitch-free bus loading during power cycles.
