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.
