The MCP23017, a 16-bit I2C GPIO expander, has always been a tasty chip. With 16 GPIOs addressable over I2C, proper push/pull outputs, software-enabled pull-ups, eight addresses, maskable ...

There can be benefits to using an I2C device instead. One of them comes when using multiple port expander chips. With cascading shift registers you must always shift in the data for the entire ...

16nm & 12nm Flip-Chip IO library with dynamically switchable 1.8V/3.3V GPIO, 5V I2C / SMBUS open-drain cell, 5V OTP cell, 1.8V & 3.3V analog cells, and associated ESD. A key attribute of this library ...

This flip-chip compatible library in Dongbu HiTek 130nm features a fail-safe GPIO, two standard GPIOs, a 5V GPI, and 5V I2C-compliant ODIO. The GFGPIO is a highly configurable 5V tolerant, ...
