74ACTQ16543 16-Bit Registered Transceiver with 3-STATE Outputs
December 1991
Revised December 1998
74ACTQ16543
16-Bit Registered Transceiver with 3-STATE Outputs
General Description
The ACTQ16543 contains sixteen non-inverting transceiv-
ers containing two sets of D-type registers for temporary
storage of data flowing in either direction. Each byte has
separate control inputs which can be shorted together for
full 16-bit operation. Separate Latch Enable and Output
Enable inputs are provided for each register to permit inde-
pendent input and output control in either direction of data
flow.
The ACTQ16543 utilizes Fairchild Quiet Series鈩?technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series鈩?fea-
tures GTO鈩?output control and undershoot corrector for
superior performance.
