SN74HC165NSR TI Shift Register | 16-SO | 8-bit, Parallel-to-Serial

Product Overview

The SN74HC165NSR 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 voltage range of 2 V to 6 V, making it suitable for interfacing with both TTL and CMOS logic families. The device features parallel inputs that allow loading of 8 bits of data simultaneously, which are then shifted out serially on the QH output. The shift register is controlled by a shift/load (SH/LD) input and a clock (CLK) input, with an overriding asynchronous clear (CLR) input. The SN74HC165NSR is offered in a 16-pin SO package (NSR suffix) and is characterized for operation from -40°C to +85°C.
