Functional Description
The AC/ACT574 consists of eight edge-triggered flip-flops
with individual D-type inputs and 3-STATE true outputs.
The buffered clock and buffered Output Enable are com-
mon to all flip-flops. The eight flip-flops will store the state
of their individual D-type inputs that meet the setup and
hold time requirements on the LOW-to-HIGH Clock (CP)
transition. With the Output Enable (OE) LOW, the contents
of the eight flip-flops are available at the outputs. When OE
is HIGH, the outputs go to the high impedance state. Oper-
ation of the OE input does not affect the state of the flip-
flops.
