The ?FCT574T devices are high-speed, low-power, octal D-type Flip-Flops
featuring separate D-type inputs for each Flip-Flop
These devices have 3-state outputs for bus-oriented applications. A buffered clock (CP) and output-enable (OE) inputs are common to all Flip-Flops
The ?FCT574T are identical to ?FCT374T, except for a flow-through pinout to simplify board design. The eight Flip-Flops
in the ?FCT574T store the state of their individual D inputs that meet the setup-time and hold-time requirements on the low-to-high CP transition. When OE is low, the contents of the eight Flip-Flops
are available at the outputs. When OE is high, the outputs are in the high-impedance state. The state of OE does not affect the state of the Flip-Flops
These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
