WebSep 17, 2016 · The 74HC595 can be controlled with only 3 pins but exposes 8 output pins. The state of those 8 output pins depends on the value of a byte previously transferred by the microcontroller via a serial interface (the 3 pins mentioned). WebThe 74HC595 consists of an 8−bit shift register and a storage register with three−state parallel outputs. It converts serial input into parallel output so that you can save IO ports of an MCU. The 74HC595 is widely used to indicate multipath LEDs and drive multi-bit segment displays.
