TOSHIBA · Logic Output Optoisolators · SO-6

TLP2761 from TOSHIBA, in a SO-6. 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 input GaAlAs infrared LED, which is driven with an input forward current IF that must not exceed the absolute maximum of 10 mA.
2 N.C. unconnected Not connected internally; the datasheet labels this pin N.C. and gives no electrical function for it.
3 Cathode passive Cathode of the input GaAlAs infrared LED, which is the return path for the input LED current.
4 GND power_in Ground reference for the detector IC; a 0.1 µF ceramic bypass capacitor must be connected between pin 6 and pin 4, placed within 1 cm of each pin.
5 VO output Totem-pole logic output of the detector, with a low-level output voltage of 0.4 V max at IO = 3.2 mA (VCC = 2.7 to 5.5 V).
6 VCC power_in Detector supply pin operating from 2.7 V to 5.5 V, which requires a 0.1 µF bypass capacitor to pin 4.
