The SN74HC595N comes in a small DIP package. Inside, you'll find an 8-bit, serial-in parallel-out shift register that supplies an 8-bit D-type storage register with parallel 3-state outputs.
It's important to note that the SN74HC595N is a drop-in replacement for the 74HC595 shift register IC and should function seamlessly in any application the previous version could.
The SN74HC595N offers several notable features:
The SN74HC595N is perfect for projects where you need to extend the number of outputs of a microcontroller. It is particularly useful in situations where you need to control a large number of LEDs or other output devices with a limited number of microcontroller pins.
