MC74ACT374

Octal DĆType FlipĆFlop

with 3ĆState Outputs

The MC74AC374/74ACT374 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.
