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 common to all
flip-flops. The eight flip-flops will store the state of their indi-
vidual D-type inputs that meet the setup and hold time re-
quirements 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. Operation of the OE
input does not affect the state of the flip-flops.
