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.","metaTitle":"Texas Instruments PCF8575PWR I²C I/O Expander, 16-bit","metaDescription":"Texas Instruments PCF8575PWR I²C I/O expander, 16-bit, 400 kHz, 2.5-5.5 V, -40 to 85°C, 24-TSSOP.
