54ACT534
Octal D Flip-Flop with TRI-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 TRI-STATE outputs for bus-oriented applications. A buff-
ered 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.
