Functional Description

The LCX374 consists of eight edge-triggered flip-flops with

individual D-type inputs and TRI-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 re-

quirements 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 Operation of the

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