TLP2601 is a photocoupler from TOSHIBA that combines a GaAℓAs IRed as the emitter and an integrated high gain, high-speed photodetector. It features an isolated line receiver, simplex/multiplex data transmission, computer-peripheral interface, microprocessor system interface, and digital isolation for A/D, D/A conversion. It is a direct replacement for HCPL−2601.
The TLP2601 is a Toshiba GaAs infrared photocoupler that combines an LED emitter with a high‑gain photodetector. It offers an open‑collector output, a Faraday shield for reduced capacitive coupling, and a common‑mode transient immunity of 1000 V/µs.
