The M74HC165 is a high speed CMOS 8-bit parallel-in serial-out shift register.
The M74HC165 is a high-speed CMOS 8-bit PISO (parallel-in-serial-out) shift register fabricated with silicon gate CMOS technology. It contains eight clocked master-slave RS flip-flops connected as a shift register, with auxiliary gating to provide overriding asynchronous parallel entry. The device is pin and function compatible with the 74 series 165.
