74HC595集成電路（IC）的移位寄存器規(guī)格書PDF中文資料

74HC595屬于集成電路（IC）的移位寄存器。由安森美半導體公司制造生產的74HC595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換數字邏輯信號形式的數據，或在數字字內移動數據位的位置。移位寄存器通常使用集成到一個設備中的一組觸發(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 擴展等應用，在這些應用中離散形式的函數可能會非常有用。

The 74HC595 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 HC595 directly interfaces with the SPI serial data port on CMOS MPUs and MCUs.
