LTV-M501-3 from Lite On, in a SOP-5-175mil. 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 | Anode | passive | Anode of the AlGaAs input LED; absolute maximum average forward input current is 20 mA (peak 40 mA at 50% duty, 1 ms pulse) and reverse input voltage is 5 V. |
| 3 | Cathode | passive | Cathode of the AlGaAs input LED; input power dissipation is limited to 36 mW absolute maximum. |
| 4 | GND | power_in | Ground reference for the detector; a 0.1 µF bypass capacitor must be connected between pin 4 and pin 6. |
| 5 | Vo | output | Open-collector logic output (LED on gives L, LED off gives H); output collector voltage is limited to -0.5 V to 20 V, output collector current to 8 mA DC (16 mA peak). |
| 6 | Vcc | power_in | Positive supply; absolute maximum -0.5 V to 30 V, recommended operating range 2.7 V to 24 V, with a 0.1 µF bypass capacitor to pin 4. |
