Functional Description

The LVX374 consists of eight edge-triggered flip-flops with

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

buffered clock and buffered Output Enable are common to

all flip-flops. The eight flip-flops 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) LOW, the contents of the

eight flip-flops are available at the outputs. When the OE is

HIGH, the outputs go to the high impedance state. Opera-

tion of the OE input does not affect the state of the flip-

flops.
