74ACT534
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The ACT534 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. The ACT534 is the same as the ACT374 except that
the outputs are inverted.
