It takes eight parallel input bits and clocks them out serially, one bit per clock pulse, with complementary outputs available. This is the standard part for adding extra digital inputs to a microcontroller without burning GPIO pins — think panel buttons, DIP switches, or encoder signals on a motor-drive board. A single element handles eight bits. The 16-SOIC package is a common footprint, easy to hand-solder or rework on a repair bench.","metaTitle":"SN74HC165DRG3 Shift Register, 8-bit, 16-SOIC, 2V-6V","metaDescription":"TI SN74HC165DRG3 8-bit parallel-in/serial-out shift register, 74HC family, 2V-6V supply, -40°C to 125°C, 16-SOIC.
