High Speed Photocoupler
Toshiba America Electronic Components, Inc., introduces its 5V, 50 MegaBaud1 (MBd) TLP117 IC photocoupler for high speed digital transmission applications. It specifically addresses applications with isolation and switching speed requirements such as system I/O interfaces and factory automation networks. The device is an optically coupled isolator consisting of a gallium aluminum arsenide (GaAlAs) light-emitting diode and an integrated high-gain, high- speed photo detector. Compared to the company’s previous generation product, this photocoupler more than doubles the switching speed, effectively reducing the propagation delay from 60 ns to 30 ns while maintaining high common mode transient immunity of +10KV/µs, and a high isolation voltage of 3.75 kVrms.
