CDDFN10-3304NA from BOURNS, in a TDFN-10-EP(2.5x2.5). 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 | CH1 | passive | I/O data line 1 protected by the TVS steering diode array (4 pF typical junction capacitance to ground, 3.3 V working voltage). |
| 2 | NC | unconnected | No connection. |
| 3 | CH3 | passive | I/O data line 3 protected by the TVS steering diode array (4 pF typical junction capacitance to ground, 3.3 V working voltage). |
| 4 | NC | unconnected | No connection. |
| 5 | VDD | power_in | Steering diode supply reference pin; leakage specified at VRWM 3.3 V with pin 5 to ground, 1 µA max. |
| 6 | NC | unconnected | No connection. |
| 7 | CH4 | passive | I/O data line 4 protected by the TVS steering diode array (4 pF typical junction capacitance to ground, 3.3 V working voltage). |
| 8 | NC | unconnected | No connection. |
| 9 | CH2 | passive | I/O data line 2 protected by the TVS steering diode array (4 pF typical junction capacitance to ground, 3.3 V working voltage). |
| 10 | NC | unconnected | No connection. |
| 11 | GND | power_in | Center tab ground pad of the DFN-10 package, the ground reference for all I/O clamping. |
