Pin Function Grouping
1 day
Looking at the datasheet of this component, can you group together pins by their functions?
for example for Power, 3v3, gnd_1 gnd_2 etc
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function.

I’ll check the component’s datasheet pin table and current project pin list, then group each physical pin once by its primary function.

I found the VQFN/RGE pin table. I’ll now apply primary-function group labels so no pin appears in more than one group.

Done. I grouped all 25 TCA9548ARGER VQFN pins from the TI datasheet, with each physical pin assigned to exactly one primary function group.
Groups applied:
- Power: VCC
- Ground: GND, EP
- Controller I²C Bus: SDA, SCL
- I²C Channels 0–7: SDx/SCx paired per channel
- Address: A0, A1, A2
- Reset: ~RESET
I also updated pin types and descriptions to match the datasheet, including pull-up guidance for the I²C and reset pins.

TCA9548ARGER Engineering Specifications
General Description
The TCA9548ARGER is a low-voltage I²C and SMBus switch manufactured by Texas Instruments. It is designed to expand and manage I²C communication networks by allowing a single master device to selectively communicate with multiple downstream buses through independent switching channels.
The device functions as a bidirectional translating switch, enabling communication between devices operating at different voltage levels while maintaining protocol compatibility. Through software control, individual channels can be enabled or disabled, providing flexible bus segmentation, address conflict resolution, and system scalability.
The TCA9548ARGER is widely used in embedded systems, industrial control equipment, data acquisition platforms, telecommunications hardware, server management systems, sensor networks, and Internet of Things applications where multiple I²C devices must be connected to a single controller.
Its low-power CMOS architecture, integrated reset functionality, and hot-insertion support make it suitable for complex digital systems requiring reliable and efficient I²C bus management.
