CY54FCT374T中文资料具有三态输出的八路 D 类寄存器数据手册TI规格书

描述 Description

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.
