The TLP115A is a small outline coupler suitable for surface mount assembly. It is designed for high speed, long distance isolated line receiver, microprocessor system interfaces, digital isolation, A/D and D/A conversion, computer-peripheral interfaces, and ground loop elimination. The coupler consists of a high output power GaAℓAs light emitting diode and an integrated high gain, high speed shielded photo detector with an output of an open collector schottky clamped transistor. The shield provides a guaranteed transient immunity specification of 1000V/µs by shunting capacirively coupled common noise to ground.
The TLP115A is a high‑speed, long‑distance isolated line receiver designed for microprocessor system interfaces, A/D and D/A conversion, and computer peripheral connections. It integrates a GaAs light‑emitting diode optically coupled to a high‑gain shielded photodetector with an open‑collector Schottky‑clamped output.
Key specifications include a minimum isolation voltage of 2500 Vrms, typical forward voltage of 1.4 V at 10 mA, and propagation delay times around 60 ns. The device operates from a 4.5‑5.5 V supply, supports up to 25 mA output current, and meets UL1577 standards. Recommended application circuits and handling precautions are also provided.
