Functional Description

The

’ACTQ16374

consists

of

sixteen

edge-triggered

flip-flops with individual D-type inputs and TRI-STATE true

outputs. The device is byte controlled with each byte func-

tioning identically, but independent of the other. The control

pins can be shorted together to obtain full 16-bit operation.

Each byte has a buffered clock and buffered Output Enable

common to all flip-flops within that byte. The description

which follows applies to each byte. Each flip-flop will store

the state of their individual D inputs that meet the setup and

hold time requirements on the LOW-to-HIGH Clock (CP

n)

transition. With the Output Enable (OE

n) LOW, the contents

of the flip-flops are available at the outputs. When OE

n is

HIGH, the outputs go to the high impedance state. Operation

of the OE

n input does not affect the state of the flip-flops.
