描述 Description

The 74AHCT595 is an advanced high speed CMOS device
that is designed to be pin compatable with 74LS low power
Schottky types.
An eight bit shift register accpets data from the serial input
(DS) on each positive transition of the shift register clock
(STCP). When asserted low the reset function ( ) sets
all shift register values to zero and is indepent of all clocks.
Data from the input serial shift register is placed in the
output register with a rising pulse on the storages resister
clock (SHCP). With the output enable ( asserted low
the 3-state outputs Q0-Q7 become active and present th
All registers capture data on rising edge and change output
on the falling edge. If both clocks are connected together
the input shift register is always one clock cycle ahead of
the output register.

简介

74AHCT595属于集成电路（IC）的移位寄存器。由制造生产的74AHCT595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。
