**HELE(Harmony Elec)** · Oscillators · SMD2520-4P

S2H008000I3CHE-T from HELE(Harmony Elec), 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 | OE | input | Output enable input: open or high (Vih min 0.7xVdd) gives oscillation output, low (Vil max 0.3xVdd) puts the output in high-Z with Idd2 max 0.01 mA. |
| 2 | GND | power_in | Ground; a 0.01 uF ceramic bypass capacitor between Vdd and GND is recommended. |
| 3 | Output | output | CMOS clock output at 8.000000 MHz, rated for CL = 15 pF with rise/fall time max 10 ns and 40-60% symmetry. |
| 4 | Vdd | power_in | Supply voltage 3.0 to 3.6 V (3.3 V typ), absolute maximum -0.5 to 4.0 V, Idd1 max 7 mA. |
