3 Description

The SN74LV595A device contains an 8-bit serial-in,

parallel-out shift register that feeds an 8-bit D-type

storage register. Both the shift register clock (SRCLK)

and storage register clock (RCLK) are positive-edge

triggered.

SN74LV595APWRG3属于集成电路（IC） > 移位寄存器。美国德州仪器公司制造生产的SN74LV595APWRG3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。
