74FCT534
Octal D Flip-Flop with TRI-STATE Outputs
General Description
The ’FCT534 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 FACT^TM FCT utilizes NSC quiet series technology
to provide improved quiet output switching and dynamic
threshold performance
FACT FCT features GTO^TM output control and undershoot
corrector in addition to a split ground bus for superior per-
formance The ’FCT534 is the same as the ’FCT374 except
that the outputs are inverted
