# 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 - **Manufacturer Part Number:** TCA9555RGER - **Materials:** Component, Material, %/wt Bond Wire, Copper, 99.9884 Bond Wire, Proprietary Materials, 0.008189 Bond Wire, Iron, 0.000682 Bond Wire, Silver, 0.002047 Die Attach Adhesive, Silver, 81.099945 Die Attach Adhesive, Epoxy, 18.900057 Lead Frame, Copper, 99.25 Lead Frame, Chromium, 0.259999 Lead Frame, Tin, 0.250003 Lead Frame, Zinc, 0.240001 Lead Frame Plating, Nickel, 95.12008 Lead Frame Plating, Gold, 0.780019 Lead Frame Plating, Palladium, 4.099904 Mold Compound, Fused Silica, 90.5 Mold Compound, Carbon Black, 0.499998 Mold Compound, Epoxy, 8.999999 Semiconductor Device, Doped Silicon, 100 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Name:** Texas Instruments - **Package or Case Code:** QFN50P500X500X100-29N - **Compliance:** RoHS,Green - **Part Type:** Integrated Circuit - **Datasheet URL:** https://storage.googleapis.com/copilot-datasheets/pdf-upload-eaa9805a5d5e8cab00b4bbae9e17beeefbd3a210fe3068aab9fe401199a2a7d0/a76389f87f99454e02256826a5ed2e703656d48adf402997459f2fd94389c794.pdf?GoogleAccessId=graviton-mvp%40appspot.gserviceaccount.com&Expires=4860351610&Signature=RMpuIwWnGTKf%2Ft65etWfSy9sZpOlTwiM7ASFDW14MFrSumVaNNVRtrR3s7v8P7Mska1e%2BbZ78GIvhIMgo%2BgCNzo79ENMi0CDQjyo43tBJGFEreXmV79AGx080W9HG25eaOONIkyW9QxfbVc3YjvvBzJ6TgM682%2Fb7N9T1ElviQkKxyJG6AAr6sB%2B1qSqdzXYzCp50zktdLZphPuDFQXNNSVq%2B37md%2BtA4rNojhYQES%2B7GSw9fgqo52JS1qV65Wma5HAyJNrrorJfsJPotf42J1TwGwYbR2Y9KhL1W0fEFM2rMHloXXb%2FMR7qJxe68iT3f2RgWZFjpH%2Bjwi0x0%2BlNKA%3D%3D - **Copies:** 1 *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/jbreidfjord-dev/tca9555rger-ecav~78](https://www.flux.ai/jbreidfjord-dev/tca9555rger-ecav~78).* --- *Generated from [https://www.flux.ai/jbreidfjord-dev/tca9555rger-ecav~78](https://www.flux.ai/jbreidfjord-dev/tca9555rger-ecav~78)*
