SN74HC166DR TI Shift Register | 16-SOIC | 8-bit, Parallel-to-Serial

Product Overview

The SN74HC166DR from Texas Instruments is a high-speed 8-bit parallel-in/serial-out shift register fabricated using advanced silicon-gate CMOS technology. It operates over a wide voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. The device features a direct overriding clear (CLR) input, serial (SER) input, and parallel data inputs (D0–D7). Data is shifted on the positive-going edge of the clock (CLK) input. The SN74HC166DR is offered in a compact 16-SOIC package, ideal for space-constrained designs.
