ECS-2018-400-BN 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: open or VIH (70% VDD min.) gives oscillation, VIL (30% VDD max.) gives no oscillation with stand-by current of 10 μA max. |
| 2 | Ground | power_in | Ground connection. |
| 3 | Output | output | HCMOS clock output driving up to 15 pF CMOS load, with VOL 10% VDD and VOH 90% VDD levels. |
| 4 | VDD | power_in | Supply voltage of +1.71 V min, +1.80 V typ, +1.89 V max. |
