CD74HC166E集成电路（IC）的移位寄存器规格书PDF中文资料

CD74HC166E属于集成电路（IC）的移位寄存器。由德州仪器制造生产的CD74HC166E移位寄存器移位寄存器是低级逻辑器件，通常用于在串行和并行方式之间转换数字逻辑信号形式的数据，或在数字字内移动数据位的位置。移位寄存器通常使用集成到一个设备中的一组触发器来实现，常用于集成度更高的逻辑器件，但仍可用于 I/O 扩展等应用，在这些应用中离散形式的函数可能会非常有用。

2 Description

The ’HC166 and ’HCT166 8-bit shift register is

fabricated with silicon gate CMOS technology. It

possesses the low power consumption of standard

CMOS integrated circuits, and can operate at speeds

comparable to the equivalent low power Schottky

device.
