# TCA9555RGER ecAV ## Description The TCA9555 is a 16-bit I/O expander for the 1.65-V to 5.5-V Vcc operation designed by Texas Instruments. It serves to enhance the general-purpose remote I/O expansion for most microcontroller families via the I2C interface. Key features of the TCA9555 include low standby-current consumption, 5-V I/O ports, 400-Khz fast I2C bus, and ESD protection. It finds applications across personal computers, servers, routers, industrial automation equipment, and products with GPIO-limited processors. ## Project Details - **Owner:** jbreidfjord-dev - **Created:** 2/1/2024 - **Last Updated:** 2/1/2024 - **Visibility:** Public - **Copies:** 1 --- *Generated from [https://www.flux.ai/jbreidfjord-dev/tca9555rger-ecav](https://www.flux.ai/jbreidfjord-dev/tca9555rger-ecav)*
