ECS-2520S33-400-FN-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 enable: the output is active when this pin is high or NC, and goes to high impedance when it is low. |
| 2 | Gnd | power_in | Ground pad for the oscillator supply return. |
| 3 | Output | output | HCMOS clock output with VOL at most 10% of Vdd and VOH at least 90% of Vdd, specified for a 15 pF load. |
| 4 | Vdd | power_in | Supply pin, +3.3 V DC nominal for this variant with ±10% tolerance. |
