I/O Expanders

ICs for increasing input/output capacity in microcontroller-based systems

I/O expanders add extra digital inputs and outputs to microcontrollers and processors without needing more pins. An I/O expander is ideal for applications like keypads, LEDs, and sensors where pin count is limited but flexibility is key. Integrated I/O expanders connect over I2C, SPI, or serial interfaces to streamline board layout and simplify wiring. Use Octopart to quickly find the I/O expander ICs or other interface components you need. You can then compare suppliers, view datasheets, and check real-time pricing and availability.
