# S3225SMD8MOSC

**SST** · Oscillators · SMD3225-4P

S3225SMD8MOSC from SST, in a SMD3225-4P. 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 | INHB | input | Output state control (tri-state): high level or open gives normal oscillator output, low level puts QOUT in high impedance; must not be tied to ground. |
| 2 | VSS | power_in | Ground. |
| 3 | QOUT | output | Oscillator output, 15pF HCMOS/TTL compatible load, high impedance when INHB is low. |
| 4 | VDD | power_in | Power supply, 3.3V±10% or 1.8V±10%, with 0.01μF bypass capacitor shown in the application circuit. |
