Quad Parallel Register with Enable
General Description
The ’F379 is a 4-bit register with buffered common Enable
This device is similar to the ’F175 but features the common
Enable rather than common Master Reset
Features
Y Edge triggered D-type inputs
Y Buffered positive edge-triggered clock
Y Buffered common enable input
Y True and complement outputs
Y Guaranteed 4000V minimum ESD protection

Functional Description
The ’F379 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 provided that the
recommended setup and hold times are observed
