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.
