The SN74HCS165DR: This 8-bit shift register accepts parallel or serial input and outputs serial data with push-pull drive, making it a drop-in for daisy-chained inputs on a microcontroller SPI or GPIO bus.
16-SOIC footprint and packaging
Housed in a 16-SOIC (3.90 mm body width) — the standard narrow SOIC footprint that matches thousands of existing PCB layouts for 8-bit shift registers and general-purpose logic. Available on Tape & Reel (TR) for automated assembly or Cut Tape (CT) for prototype and low-volume builds; the reel quantity sets the MOQ floor for production orders.
Compliance and regulatory pass-through
ROHS3 compliant — the part ships without the six original restricted substances plus the four phthalates, clearing EU and global regulatory gates without an exemption certificate. The 74HCS series is Texas Instruments' high-speed CMOS logic family with Schmitt-trigger inputs — the same pinout as the legacy 74HC165 but with improved noise immunity on the clock and data lines.
