Description: The SN74HC595N is a simple 8-bit shift register IC. Simply put, this shift register is a device that allows additional inputs or outputs to be added to a microcontroller by converting data between parallel and serial formats. Your chosen microprocessor is able to communicate with the The SN74HC595N using serial information then gathers or outputs information in a parallel (multi-pin) format. Essentially it takes 8 bits from the serial input and then outputs them to 8 pins.

This small DIP packaged IC contains an 8-bit, serial-in parallel-out shift register that feeds an 8-bit D-type storage register with parallel 3-state outputs.

Note: This is a drop-in replacement for the 74HC595 shift register IC and should function just fine in any application the previous version could.

Features:

  • 8-Bit Serial-In, Parallel-Out Shift
  • 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

  • You have a typo in the description. “Simply put, this shift register is a device that allows additional inputs or outputs to be added to a microcontroller by converting data between parallel and serial formats.” This shift register cannot function as a shift-in register and therefore does not add additional inputs.
