ECS-TXO-2520-33-240-AN-TR from ECS, in a SMD2520-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Tri-state | input | Tri-state control: output is active when this pin is high or not connected, and low disables the output to Hi-Z. |
