74ABT16543 16-Bit Registered Transceiver with 3-STATE Outputs is a 16-bit bidirectional data bus transceiver produced by American Fairchild Semiconductor Corporation. The chip adopts a 56-pin SSOP package, and has back-to-back registers, separate Latche Enable, Output Enable, A, B output pins, high impedance glitch-free bus loading and other features.
The ABT16543 is a 16-bit transceiver containing two sets of D-type latches for temporary data storage in either direction. It features separate Latch Enable and Output Enable inputs for each register, allowing independent control of inputting and outputting. The device supports both A-to-B and B-to-A data flow with guaranteed latchup protection.
