TLP280 and TLP280-4 are very small and thin couplers, suitable for surface mount assembly in applications such as PCMCIA fax modem, programmable controllers.
The TLP280 and TLP280-4 are compact surface‑mount GaAs infrared photocouplers designed for applications such as PCMCIA fax modems and programmable controllers. They consist of a photo‑transistor optically coupled to an infrared emitting diode and can operate directly from AC input current.
