LM567CDRG from HANSCHIP semiconductor, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTPUT FILTER | passive | Low-pass loop filter capacitor connection. External capacitor C2 to ground sets the output filter time constant and affects the detection bandwidth. |
| 2 | LOOP FILTER | passive | Loop low-pass filter capacitor connection. External capacitor C3 to ground sets the loop filter bandwidth (detection bandwidth of the tone decoder). |
| 3 | INPUT | input | Tone input. AC-coupled input signal to be detected; input impedance approximately 20 kΩ. Minimum input signal for detection typically 20 mVrms. |
| 4 | V+ | power_in | Positive supply voltage. Operating range 4.75 V to 9 V (absolute maximum 10 V). Supply current typically 7 mA at 5 V. |
| 5 | TIMING R | passive | Timing resistor connection. External resistor R1 (2 kΩ to 20 kΩ) from this pin to V+ sets the VCO center frequency together with C1 on pin 6. Center frequency f0 ≈ 1/(1.1·R1·C1). |
| 6 | TIMING C | passive | Timing capacitor connection. External capacitor C1 from this pin to ground sets the VCO center frequency in combination with R1 on pin 5. Frequency range 0.01 Hz to 500 kHz. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | OUTPUT | output | Open-collector logic output. Sinks up to 100 mA (typ) to ground when an in-band tone is detected; otherwise high-impedance. Requires external pull-up resistor to V+ (up to 15 V). |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
lm567cdrg.step |

1.9 MB | You want the part with LM567CDRG already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 461 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
