TLP127 is a high noise, high isolation optical coupler produced by Toshiba Corporation. It uses a small, thin mini flat package and is suitable for applications such as electronic computer I/O interfaces, programmable controllers, DC output modules, electronic button telephone systems, and telephone exchanges.
The TLP127 is a miniature flat‑package optocoupler that combines a GaAs infrared LED with a phototransistor for high noise immunity and high isolation. It is suited for programmable controller output modules, electronic telephone systems, and other 100 VDO applications.
