DESCRIPTION The LTV-0501 consists of a high efficient AlGaAs Light Emitting Diode and a high speed optical detector. This design provides excellent AC and DC isolation between the input and output sides of the Optocoupler. Connection for the bias of the photodiode improves the speed that of a conventional phototransistor coupler by reducing the base-collector capacitances. A guaranteed common mode transient immunity is up to 1KV/µsec. 1.1 Features
