MC74HC589A数据手册集成电路（IC）的移位寄存器规格书PDF

描述 Description

High-Performance Silicon-Gate CMOS The MC74HC589A is similar in function to the HC597, which is not a 3-state device. The device inputs are compatible with standard CMOS outputs, with pullup resistors, they are compatible with LSTTL outputs. This device consists of an 8-bit storage latch which feeds parallel data to an 8-bit shift register. Data can also be loaded serially (see Function Table). The shift register output, QH, is a three-state output, allowing this device to be used in bus-oriented systems. The HC589A directly interfaces with the Motorola SPI serial data port on CMOS MPUs and MCUs.

• Pb-Free Packages are Available

简介

MC74HC589A属于集成电路（IC）的移位寄存器。由制造生产的MC74HC589A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。
