TLP627,TLP627-2,TLP627-4 is a photocoupler produced by TOSHIBA. This product consists of a light-emitting diode and a phototransistor, which has an integral base-emitter resistor, high switching speed and high temperature characteristics.
The TLP627 series optocouplers from Toshiba integrate a GaAs infrared emitting diode with a Darlington‑connected phototransistor, offering high isolation and fast switching. The TLP627‑2 provides two isolated channels in an 8‑lead DIP, while the TLP627‑4 offers four channels in the same package.
