MC74HC589AN集成电路（IC）的移位寄存器规格书PDF中文资料

MC74HC589AN属于集成电路（IC）的移位寄存器。由安森美半导体公司制造生产的MC74HC589AN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。

8-Bit Serial or Parallel-Input/Serial-Output Shift Register with 3-State Output

High−Performance Silicon−Gate CMOS

The MC74HC589A 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 the Function Table). The shift register output, QH, is a 3−state output, allowing this device to be used in bus−oriented systems.

The HC589A directly interfaces with the SPI serial data port on CMOS MPUs and MCUs.
