M74HC166屬于集成電路（IC）的移位寄存器。由意法半導(dǎo)體集團制造生產(chǎn)的M74HC166移位寄存器移位寄存器是低級邏輯器件，通常用于在串行和并行方式之間轉(zhuǎn)換數(shù)字邏輯信號形式的數(shù)據(jù)，或在數(shù)字字內(nèi)移動數(shù)據(jù)位的位置。移位寄存器通常使用集成到一個設(shè)備中的一組觸發(fā)器來實現(xiàn)，常用于集成度更高的邏輯器件，但仍可用于 I/O 擴展等應(yīng)用，在這些應(yīng)用中離散形式的函數(shù)可能會非常有用。

描述 Description

The M54HCxxx and M54HCTxxx series are composed of over 90 types of high speed CMOS functions specifically designed to meet the radiation requirements of the aerospace industry. It includes a large set of gates, Flip-Flops, Multiplexers, Counters, Bus interface and several other functions. The radiation hardness, the single event latch-up (SEL) immunity and the housing in hermetic packages of all types of both series make them ideally suited for use in the most difficult environmental conditions.
