SN74AHC595PW集成电路（IC）的移位寄存器规格书PDF中文资料

SN74AHC595PW属于集成电路（IC）的移位寄存器。由德州仪器制造生产的SN74AHC595PW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。

3 Description

The SN74AHC595 device contains an 8-bit serial-in,

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

storage register. The storage register has parallel 3-

state outputs. Separate clocks are provided for both

the shift and storage registers. The shift register has a

direct overriding clear ( SRCLR) input, a serial (SER)

input, and a serial output for cascading. When the

output-enable ( OE) input is high, all outputs except

QH′ are in the high-impedance state.
