74ACTQ823
Quiet Series™ 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™ technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series™ features
GTO™ output control and undershoot corrector in addition
to a split ground bus for superior performance.
Features
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Inputs and outputs on opposite sides of package allow
easy interface with microprocessors
s Improved latch-up immunity
s Has TTL-compatible inputs
