Web23 okt. 2024 · The data sheet of the 74HC595 states that each output can deliver at least 35mA because this is the allowed maximum output current. This is clearly more then the allowed 25mA of the µC. There is another limit: the 74HC595 must not provide more than 70mA in total. So you need a resistor per line. Web74HC595和74hc164一样是在单片机系统中常用的芯片之一他的作用就是把串行的信号转为并行的信号,常用在各种数码管以及点阵屏的驱动芯片, 使用74HC595可以节约单片机mcu的io口资源,用3个io就可以控制8个数码管的引脚,他还具有一定的驱动能力,可以免掉三极管等放大电路,所以这块芯片是驱动 ... rolling fork mississippi tornado pictures

Both the shift and storage register have separate clocks. The device features a serial input (DS) and a serial output (Q7S) to enable cascading and an asynchronous reset MR input. A LOW on MR will reset the shift register. WebThe datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state." In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. You can link multiple registers together to extend your output even more. rolling fork ms church of christ
