It adds eight general-purpose I/O lines to a host microcontroller over a two-wire I²C bus running at 400 kHz. The part includes a power-on reset (POR) feature and a dedicated interrupt output that signals the host when an input state changes — useful for polling-free keypad or sensor monitoring. ## Supply, temperature, and output drive — what they mean for your BOM Supply range of 2.3 V to 5.5 V. Operating temperature -40°C to 85°C. ## Package and mounting Housed in a 16-TSSOP (4.40 mm width) package, surface-mount only. Available in Tape & Reel (TR) or Cut Tape (CT) — the reel option suits automated pick-and-place; Cut Tape works for prototypes and small-batch builds.","metaTitle":"NXP PCA8574PW,118 I2C GPIO Expander, 8 I/O, 400 kHz","metaDescription":"NXP PCA8574PW,118 I2C GPIO expander with 8 I/O, 400 kHz clock, interrupt output, 2.3V–5.5V supply, -40°C to 85°C.
