74ACTQ821
Quiet Series鈩?10-Bit D-Type Flip-Flop
with 3-STATE Outputs
General Description
The ACTQ821 is a 10-bit D-type flip-flop with non-inverting
3-STATE outputs arranged in a broadside pinout. The
ACTQ821 utilizes Fairchild鈥檚 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.
