Part Verification and Datasheet Update
3 days
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 group each MCP4461 pin once by its primary datasheet function, then verify the terminal metadata afterward.
Thought for 1 min 6 sec

I applied the grouping, then saw the platform suggested more standard group labels; I’m normalizing them now so the metadata is cleaner and still one group per pin.
Thought for 45 sec
3 days
Done — I grouped all 20 MCP4461 pins by their primary datasheet function, with each physical pin assigned to exactly one group.
Groups applied:
- Power: VDD
- Ground: VSS
- I2C: SCL, SDA
- Control Bus: HVC/A0, A1, ~WP, ~RESET
- Analog: P0A/P0W/P0B, P1A/P1W/P1B, P2A/P2W/P2B, P3A/P3W/P3B
I also updated the terminal Section, Pin Type, and Pin Description metadata from the datasheet and verified the final grouping.
