Functional Description

The ’ACT534 consists of eight edge-triggered flip-flops with

individual D-type inputs and TRI-STATE complementary

outputs The buffered clock and buffered Output Enable are

common to all flip-flops The eight flip-flops will store the

state of their individual D inputs that meet the setup and

hold times 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 the

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
