Functional Description

The ’F378 consists of six edge-triggered D-type flip-flops

with individual D inputs and Q inputs The Clock (CP) and

Enable (E) inputs are common to all flip-flops

When the E input is LOW new data is entered into the

When the E input is HIGH the register will retain the present

data independent of the CP input
