M74HC595YTTR集成电路（IC）的移位寄存器规格书PDF中文资料

M74HC595YTTR属于集成电路（IC）的移位寄存器。由意法半导体集团制造生产的M74HC595YTTR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。

描述 Description

The M74HC595 device is a high speed CMOS

8-bit shift register with output latches (3-state)

fabricated with silicon gate C2MOS technology.

This device contains an 8-bit serial in, parallel out

shift register that feeds an 8-bit D-type storage

register. The storage register has 8 3-state

outputs. Separate clocks are provided for both the

shift register and the storage register.

The shift register has direct overriding clear, serial

input, and serial output (standard) pins for

cascading. Both the shift register and storage

register use positive edge triggered clocks. If both

clocks are connected together, the shift register

state will always be one clock pulse ahead of the

storage register.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
