Functional Description
The ’AC/’ACT821 consists of ten D-type edge-triggered
flip-flops. The buffered Clock (CP) and buffered Output En-
able (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 im-
pedance state. Operation of the OE input does not affect the
state of the flip-flops.
The ’AC/’ACT821 is functionally and pin compatible with the
AM29821.

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 recom-
