MC74AC374
MC74ACT374
Octal D Type Flip Flop
with 3 State 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.
