Functional Description
The ABT16374 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 (CP
transition. With the Output Enable (OE
tents of the flip-flops are available at the outputs. When
