HD74AC374/HD74ACT374
Octal D-Type Flip-Flops with 3-State Output
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.
Features
Buffered Positive Edge-Triggered Clock
3-State Outputs for Bus-Oriented Applications
Outputs Source/Sink 24 mA
