TLP280 and TLP280-4 is a photocoupler produced by TOSHIBA. It is suitable for surface mount assembly and can be used in PCMCIA fax modems, programmable controllers, etc.
The TLP280 and TLP280-4 are very small, thin optocouplers that combine a GaAs infrared emitting diode with a phototransistor. They are designed for surface‑mount assembly and are suitable for applications such as PCMCIA modems and programmable controllers.
