Product details

16-bit I²C I/O expansion in 24-TSSOP

The PCF8575PWR: Each I/O can sink up to 25 mA or source 1 mA, sufficient for driving LEDs, relays, or logic inputs without external buffers in many control-panel and sensor-interface designs. An interrupt output (INT) signals the host when any input state changes, eliminating the need for continuous polling and reducing bus traffic in event-driven systems.

Package and board-fit

The Tape & Reel (TR) and Cut Tape (CT) packaging options suit both high-volume pick-and-place and prototype or low-volume builds.

The device is ROHS3 compliant, meeting the EU RoHS directive for lead-free soldering processes.
