TLP115 is a small outline coupler suitable for surface mount assembly. It consists of a GaAℓAs light emitting diode optically coupled to an integrated high gain, high speed shielded photo detector. The output is an open collector schottky clamped transistor. The product features high speed, long distance isolated line receiver, digital isolation, A/D and D/A conversion, computer−peripheral interfaces, and ground loop elimination.
The TLP115 is a miniature surface‑mount photocoupler that combines a GaAs infrared LED with a high‑gain shielded photodetector. It provides digital isolation for A/D and D/A conversion, computer‑peripheral interfaces, and ground‑loop elimination.
The document lists maximum ratings, electrical and switching characteristics, recommended operating conditions, and usage restrictions. Key parameters include isolation voltage, input thresholds, propagation delay, and typical forward voltage curves, helping designers integrate the device safely into electronic systems.
