54ACT 74ACT534
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
