SN74LS595DR集成电路（IC）的移位寄存器规格书PDF中文资料

SN74LS595DR属于集成电路（IC）的移位寄存器。由德州仪器制造生产的SN74LS595DR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。

Accurate Shift Frequency:

DC to 20 MHz

description

These devices each contain 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 ({'LS595} or open-collector {‘LS536! outputs.

Separate clocks are provided for both the shift register

and the storage register. The shift register has a

direct-overriding clear, serial input, and serial output

pins for cascading.

Both the shift register and storage register clocks are

positive-edge triggered. If the user wishes 10 connect

both clocks together, the shift register state will always

be one clock pulse ahead of the storage register.
