# TCA9555PWR ## Description The TCA9555 is a 16-bit I/O expander for the I2C bus, designed for voltage operation from 1.65 V to 5.5 V. It provides general-purpose remote I/O expansion for most microcontroller families through the I2C interface. This device features low standby- current consumption, 5-V tolerant I/O ports, and an open-drain active-low interrupt output. It is commonly used for controlling LEDs, controlling enable or reset signals of other devices, and reading the outputs of other devices or buttons. ## Project Details - **Owner:** kerry - **Created:** 2/13/2024 - **Last Updated:** 2/13/2024 - **Visibility:** Public - **Package or Case Code:** TSSOP65P640X120-24 - **Manufacturer Name:** Texas Instruments - **Manufacturer Part Number:** TCA9555PWR - **Part Type:** Integrated Circuit - **Part Type:** Integrated Circuit - **Compliance:** RoHS & Green *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/kerry/tca9555pwr](https://www.flux.ai/kerry/tca9555pwr).* --- *Generated from [https://www.flux.ai/kerry/tca9555pwr](https://www.flux.ai/kerry/tca9555pwr)*
