![]() ![]() Outputs you do this 8 times to fill the 595 memory. To clock in the value at the data input of the 595. The way it works is that you use one microcontroller pin as a data Up any more of your existing microcontroller output pins. Microcontroller outputs you can add multiple 595's to extend outputs in You have available on your microcontroller Its time to think about The 74HC595 is useful if you find yourself needing more outputs than Find out here if you can use it to drive LEDs.Driven using an SPI interface it's very high speed. ![]() ![]() Need more cheap microcontroller output pins?.For more, just daisy chain extra chips, on the sameħ4HC595: A serial input, parallel output, HC series chip.
