TLP115 is a high performance, high speed optical coupler produced by TOSHIBA. It is suitable for applications such as microprocessor system interfaces, digital isolation, A/D and D/A conversion.
The TLP115 is a miniature surface‑mount GaAs infrared photocoupler with a high‑gain shielded detector and an open‑collector output. It provides isolation up to 2500 Vrms and is suited for digital isolation in A/D, D/A conversion, computer‑peripheral interfaces and ground‑loop elimination.
The document lists maximum ratings, electrical parameters, switching characteristics, test circuits and usage restrictions, giving designers the necessary information to integrate the device safely into electronic systems.
