74F379
Quad Parallel Register with Enable
General Description
The 74F379 is a 4-bit register with buffered common
Enable. This device is similar to the 74F175 but features
the common Enable rather than common Master Reset.

Functional Description
The 74F379 consists of four edge-triggered D-type flip-
flops with individual D inputs and Q and Q outputs. The
Clock (CP) and Enable (E) inputs are common to all flip-
flops. 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, pro-
vided that the recommended setup and hold times are
observed.
