产品描述

The \x92FCT374T 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 eight flip-flops in the \x92FCT374T 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.
