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.
