NXP PCF8574AT3518 I/O Expander
The PCF8574AT3518 is a remote 8-bit I/O expander utilizing the I2C-bus interface, supporting 100 kHz standard mode with low power consumption of 2.5 μA. It features eight quasi-bidirectional ports that default to inputs on power-up, capable of being assigned as inputs or outputs for driving LEDs, indicators, or monitoring signals. Its open-drain interrupt output alerts the system to I/O changes, optimizing microcontroller polling. The device operates between 2.5 V and 6 V, supports up to 128 I/Os with multiple units on the bus, and is suitable for industrial, medical, and consumer applications requiring reliable remote I/O expansion.
