SN74HC165N TI Shift Register | 16-PDIP | 8-bit, Parallel-to-Serial

Product Overview

The SN74HC165N from Texas Instruments is a high-speed 8-bit parallel-load shift register fabricated using advanced silicon-gate CMOS technology. It operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. The device features parallel inputs that allow loading of 8 bits of data, which can then be shifted out serially via the QH output. The shift/load (SH/LD) input selects between parallel load and shift modes. The clock input (CLK) and clock inhibit (CLK INH) provide flexible control for synchronous operation. The SN74HC165N is offered in a 16-pin PDIP package, ideal for through-hole mounting in prototyping and legacy designs.
