74LCX16374 Datasheet, PDF (3/10 Pages) Fairchild Semiconductor – Low Voltage 16-Bit D-Type Flip-Flop with 5V Tolerant Inputs and Outputs

Functional Description
The LCX16374 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_n)
transition. With the Output Enable (OE_n) LOW, the con-
tents 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.
