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.
