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

to provide improved quiet output switching and dynamic

threshold performance

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
