74FCT534

General Description
The 74FCT534 is a high-speed, low-power octal D-type flipflop featuring separate D-type inputs for each flip-flop and TRI-STATE outputs for bus-oriented applications. A buffered 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 GTOTM output control and undershoot corrector of the 74FCT534 in addition to a split ground bus for superior performance. The 'FCT534 is the same as the 'FCT374 except that the outputs are inverted.


Functional Description
The 74FCT534 consists of eight edge-triggered flip-flops with individual D-type inputs and TRI-STATE complementary outputs. The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold times requirements on the LOW-to-HIGH Clock (CP) transition. With the Output Enable (OE) LOW of the 74FCT534, the contents of the eight flip-flops are available at the outputs. When the OE is HIGH, the outputs go to the high impedance state. Operation of the OE input does not affect the state of the flip-flops.
