The PCA8574APW,118 is an 8-bit general-purpose remote I/O expander designed for use with the I2C-bus. It allows for expansion of I/O capabilities in systems requiring additional digital inputs or outputs.
This device operates between 2.3V and 5.5V, with I/Os that are tolerant up to 5.5V. It features an 8-bit quasi-bidirectional port that can be configured as either an input or an output. The I2C-bus interface supports a 400 kHz Fast-mode speed. The latched outputs have a 25 mA sink capability, suitable for directly driving LEDs.
The PCA8574APW,118 includes an active-low open-drain interrupt output that can signal the microcontroller when an input state changes, reducing the need for constant polling. It supports eight programmable slave addresses via three address pins, allowing multiple devices on the same bus. The device defaults to inputs at power-up with a weak internal pull-up.
Packaged in a 16-TSSOP, this I/O expander is suitable for surface mounting. Its operating temperature range is -40°C to 85°C.
