Functional Description

The ACT16374 consists of sixteen edge-triggered flip-flops

with individual D-type inputs and 3-STATE true outputs.

The device is byte controlled with each byte functioning

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 com-

mon 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 (CPn)

transition. With the Output Enable (OEn) LOW, the con-

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

OEn is HIGH, the outputs go to the high impedance state.

Operation of the OEn input does not affect the state of the

flip-flops.
