MC74HC595ADG集成电路（IC）的移位寄存器规格书PDF中文资料

MC74HC595ADG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MC74HC595ADG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-Input/Serial or Parallel-Output Shift Register with Latched 3-State Outputs

The MC74HC595A consists of an 8−bit shift register and an 8−bit D−type latch with three−state parallel outputs. The shift register accepts serial data and provides a serial output. The shift register also provides parallel data to the 8−bit latch. The shift register and latch have independent clock inputs. This device also has an asynchronous reset for the shift register.

The HC595A directly interfaces with the SPI serial data port on CMOS MPUs and MCUs.
