MC14021B数据手册集成电路（IC）的移位寄存器规格书PDF

描述 Description

The MC14014B and MC14021B 8-bit static shift registers are constructed with MOS P-channel and N-channel enhancement mode devices in a single monolithic structure. These shift registers find primary use in parallel-to-serial data conversion, synchronous and asynchronous parallel input, serial output data queueing; and other general purpose register applications requiring low power and/or high noise immunity.

特性 Features

• MC14021B Pin-for-Pin Replacement for CD4021B
• Pb-Free Packages are Available*

简介

MC14021B属于集成电路（IC）的移位寄存器。由制造生产的MC14021B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。
