Functional Description

Truth Table

The 74F379 consists of four edge-triggered D-type flipflops with individual D inputs and Q and Q outputs. The Clock CP and Enable E inputs are common to all flipflops. When the E is input HIGH, the register will retain the present data independent of the CP input. The Dn and E inputs can change when the clock is in either state, provided that the recommended setup and hold times are observed.
