74ACTQ823
Quiet Series鈩?9-Bit D-Type Flip-Flop
with 3-STATE Outputs
General Description
The ACTQ823 is a 9-bit buffered register. It features Clock
Enable and Clear which are ideal for parity bus interfacing
in high performance microprogramming systems. The
ACTQ823 utilizes Fairchild Quiet Series鈩?technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series鈩?features
GTO鈩?output control and undershoot corrector in addition
to a split ground bus for superior performance.
