8-bit shift register for 5V logic expansion
The SN74AHCT595PWR: The single-element 8-bit architecture accepts serial data and latches it to parallel outputs, with a tri-state output enable for bus sharing.
The 4.5V–5.5V supply range is tight—this part is designed for regulated 5V rails, not 3.3V or battery-powered circuits. If your system runs a 5V bus, the AHCT family gives you the input thresholds (TTL-compatible) and output drive of a standard 5V logic part.
The supplier device package is 16-TSSOP; the listing also supports Cut Tape (CT) for prototyping quantities alongside Tape & Reel for production.
