While designed for measurement parameters like Voltage and Current, PSPICE programs are not comfortable with evaluating or simulating components in photometric units. This application note provides guidelines for using PSPICE to model phototransistor optocouplers....

CTR is a key parameter in measuring transistor optocoupler performance. Normally expressed as a percentage, CTR is the ratio of the amount of current applied to the optocoupler's LED to the collector current received. This application note provides a method for simulating the effects of various...

This application note provides a reference design for a flexible, high power RS485 interface using NEC's PS9821 digital optocouplers and an LMS1487 transceiver from National Semiconductor....
