54ACTQ821
Quiet Series 10-Bit D Flip-Flop with TRI-STATE ® Outputs
General Description
Features
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 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.
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

54ACTQ821 Quiet Series 10-Bit D Flip-Flop with TRI-STATE Outputs
August 1998
Functional Description
The ACTQ821 consists of ten D-type edge-triggered
flip-flops. The buffered Clock (CP) and buffered Output Enable (OE) are common to all flip-flops. The flip-flops will store
the state of their individual D inputs that meet the setup and
hold time requirements on the LOW-to-HIGH CP transition.
With OE LOW the contents of the flip-flops are available at
the outputs. When OE is HIGH the outputs go to the high impedance state. Operation of the OE input does not affect the
state of the flip-flops.
The ACTQ821 is functionally and pin compatible with the
AM29821.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. National does not recommend operation of FACT ® circuits outside databook specifications.
Note 2: All commercial packaging is not recommended for applications requiring greater than 2000 temperature cycles from −40˚C to +125˚C.
