Description
The HD74AC374/HD74ACT374 is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for
each flip-flop and 3-state outputs for bus-oriented applications. A buffered Clock (CP) and Output Enable (OE) are
common to all flip-flops.

Functional Description
The HD74AC374/HD74ACT374 consists of eight edge-triggered flip-flops with individual D-type inputs and 3-state
true outputs. The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will
store the state of their individual D inputs that meet the setup and hold time requirements on the Low-to-High Clock
(CP) transition. With the Output Enable (OE) Low, the contents of the eight flip-flops are available at the outputs.
When the OE is High, the outputs go to the high impedance state. Operation of the OE input does not affect the state of
the flip-flops.
