MOTOROLA MC74ACT378D Parallel d register with enable Datasheet

PARALLEL
D REGISTER
WITH ENABLE
The MC74AC378/74ACT378 is a 6-bit register with a buffered common Enable.
This device is similar to the MC74AC174/74ACT174, but with common Enable
rather than common Master Reset.

MC74AC378 MC74ACT378
FUNCTIONAL DESCRIPTION
The MC74AC378/74ACT378 consists of six edgetriggered D-type flip-flops with individual D inputs and Q
outputs. 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
register on the LOW-to-HIGH transition of the CP input. When
the E input is HIGH, the register will retain the present data
independent of the CP input.
