{"title":"74HC595 Shift Register - 3 pack","handle":"74hc595-shift-register-3-pack","url":"/products/74hc595-shift-register-3-pack","description":"A pack of three 74HC595 shift register ICs. These chips take a serial input (SPI) of one byte and output those 8 bits onto 8 digital output pins. Chain multiple chips together by connecting the serial output of one to the serial input of the next — three chips give you 24 digital outputs from just 3 microcontroller pins.\n\nDIP package for easy breadboard and perfboard use. Each output can source approximately 20mA, making them ideal for driving LEDs directly or switching power transistors for solenoids and motors.\n\nKey Features\n\n\n3× 74HC595 ICs – 8-bit serial-in, parallel-out shift registers\n\nChainable – Daisy-chain for 16, 24, or more outputs\n\n~20mA Per Output – Drive LEDs directly or switch transistors\n\nSPI Interface – Only 3 microcontroller pins needed\n\nDIP-16 Package – Breadboard and perfboard compatible\n\n\nAlso Available\n\n74HC595 8-Bit Serial-Parallel IC (single)\n\n\nIdeal For\n\nLED arrays and matrix displays\nOutput expansion for Arduino and microcontrollers\nDriving solenoids and motors via transistors\n\n\nPackage Contents\n\n3× 74HC595 shift register ICs\n\n\nResources\n\nArduino ShiftOut Tutorial\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12390,"title":"Default Title","sku":"AF-450","price":5.96,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":67,"option1":"Default Title"}]}
