OctalD Flip-Flop with TRI-STATEÉ Outputs
General Description
The ’FCT534isa high-speed, low-power octal D-typeflip-
flop featuring separate D-type inputsfor each flip-flopand
TRI-STATE outputsfor bus-oriented applications.A buff-
ered Clock (CP)and Output Enable (OE)are commontoall
flip-flops. FACTTM FCT utilizes NSC quiet series technology provide improved quiet output switching and dynamic
threshold performance.
FACT FCT features GTOTM output control and undershoot
correctorin additiontoa split groundbusfor superior per-
formance.The ’FCT534isthe sameasthe ’FCT374 except
thatthe outputsare inverted.
