ECS-2520Q-18-260-BS-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 high or not connected, and high impedance when low. |
| 2 | Gnd | power_in | Ground connection. |
| 3 | Output | output | HCMOS clock output driving 15 pF with VOL max 10% Vdd and VOH min 90% Vdd. |
| 4 | Vdd | power_in | Supply voltage of +1.8 V for this variant (code 18), Vdd ±5%. |
