TLP2631 is a photocoupler from Toshiba. It consists of a pair of GaAℓAs light emitting diodes and an integrated high gain, high speed photodetector. The output is an open collector, Schottky clamped transistor. The device has overvoltage, overcurrent and overtemperature protection functions, and can be used for digital isolation, A/D, D/A conversion and other applications.
The TLP2631 is a dual GaAs infrared photocoupler from Toshiba, featuring a high‑gain photodetector and an open‑collector output. It is supplied in an 8‑lead DIP package and is intended for isolated line‑receiver applications such as computer‑peripheral interfaces and microprocessor systems.
The document lists absolute maximum ratings, recommended operating conditions, electrical and switching characteristics, test circuits, and safety restrictions. Key parameters include a 2500 Vrms isolation voltage, 5 mA input current threshold, 20 mA forward current per channel, and typical propagation delays of 5 ns.
