Product Overview
The SN74LVC165APWR from Texas Instruments is an 8-bit parallel-load shift register designed for 1.65V to 3.6V VCC operation. It features a wide operating voltage range, low power consumption, and high-speed performance, making it suitable for a variety of digital systems. The device accepts parallel data inputs and shifts them out serially, controlled by a shift/load (SH/LD) input and a clock (CLK) input. The SN74LVC165APWR is available in a 16-pin TSSOP package, offering a compact solution for space-constrained applications.
