The SN74HC595N is an 8-bit shift register IC. This compact device enables the addition of extra inputs or outputs to a microcontroller by transposing data between parallel and serial formats. It communicates with your selected microcontroller using serial information, then collects or outputs information in a parallel (multi-pin) format. In simpler terms, it takes 8 bits from the serial input and then outputs them to 8 pins.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: * An 8-Bit Serial-In, Parallel-Out Shift * A Wide Operating Voltage Range of 2 V to 6 V * High-Current 3-State Outputs Can Drive Up to 15 LSTTL Loads * Low Power Consumption: 80-μA * ±6-mA Output Drive at 5 V 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.For additional information and guidance, Sparkfun provides a comprehensive Shift Register Tutorial and a 7-Segment Library.
