MC74HC597A集成电路（IC）的移位寄存器规格书PDF中文资料

MC74HC597A属于集成电路（IC）的移位寄存器。由安森美半导体制造生产的MC74HC597A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。

The MC74HC597A is identical in pinout to the LS597. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

This device consists of an 8−bit input latch which feeds parallel data to an 8−bit shift register. Data can also be loaded serially.

The HC597A is similar in function to the HC589A, which is a 3−state device.
