54ACTQ821
Quiet Series 10-Bit D Flip-Flop with TRI-STATE^® Outputs
General Description
The ACTQ821 is a 10-bit D flip-flop with non-inverting
TRI-STATE outputs arranged in a broadside pinout. The
ACTQ821 utilizes NSC Quiet Series technology to guaran-
tee 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
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Non-inverting TRI-STATE outputs for bus interfacing
n 4 kV minimum ESD immunity
n Outputs source/sink 24 mA
n Functionally identical to the AM29821
