DM74LS574WMX

Octal D-Type Flip-Flop with 3-STATE Outputs

Fairchild Semiconductor 

Functional Description

The DM74LS574 consists of eight edge-triggered flip-flops

with individual D-type inputs and 3-STATE true outputs.

The buffered clock and buffered Outputs Enable are com-

mon to all flip-flops. The eight flip-flops will store the state

of their individual D inputs that meet the setup and hold

times requirements on the LOW-to-HIGH Clock (CP) tran-

sition. 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.
