74ALVCH16374

Low Voltage 16-Bit D-Type Flip-Flop with Bushold

Fairchild Semiconductor 

Functional Description

The 74ALVCH16374 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 func-

tioning identically, but independent of the other. The control

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

Each clock 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 I inputs that

meet the setup and hold time requirements on the

LOW-to-HIGH Clock (CPn) transition. With the Output

Enable (OEn) LOW, the contents of the flip-flops are avail-

able at the outputs. When OEn is HIGH, the outputs go to

the high impedance state. Operations of the OEn input

does not affect the state of the flip-flops.

Byte 1 (0:7)

Byte 2 (8:15)
