74ACTQ821
Quiet Series 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’s 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 Non-inverting 3-STATE outputs for bus interfacing
s 4 kV minimum ESD immunity
s Outputs source/sink 24 mA
