8-bit PISO shift register in 16-TSSOP
The SN74HCT165PWR is an 8-bit parallel-in/serial-out shift register from Texas Instruments' HCT logic family. It accepts eight parallel data inputs and shifts them out serially on a single line, driven by a clock input — a standard building block for expanding digital inputs on a microcontroller or FPGA without multiplying I/O pins. Operating from a 4.5V to 5.5V supply, it is designed for 5V TTL-compatible systems. The -40°C to 125°C temperature range covers industrial and automotive under-hood environments, making it suitable for factory-floor controllers, engine management ECUs, and outdoor telecom gear.
Package and supply posture
Housed in a 16-TSSOP package (4.40mm width), the SN74HCT165PWR is a surface-mount part supplied on tape and reel for automated pick-and-place assembly. The small footprint suits dense PCB layouts where board space is at a premium. Texas Instruments lists this part as Active in production. Quoted to order against BOM quantities; lead time and pricing confirmed at RFQ.
