I2C General Purpose I/O (GPIO)

Our industry-leading General Purpose I/O (GPIO) expanders provide 4, 8, 16, 24, or 40 general-purpose I/O pins for the CPU via the I2C-bus to help designers reduce board space and complexity while simplifying software development and lowering overall system cost.

Our agile I2C GPIO includes features to eliminate external components as pull-up resistors, open-drain outputs, output drive control, and input latches to permit faster software development and more robust firmware performance.
