The LTV-357T-C is a transistor output optocoupler manufactured by Lite-On with a high dielectric strength and excellent common mode transient immunity. It is designed for galvanic isolated interface between a controller and its peripherals, or between digital and analog circuitry. The optocouplers have a thin-film beam-lead transistor output which offers high insulation resistance between input and output. These optocouplers have an isolation voltage of 5300Vrms and a current transfer ratio ranging from 2.0 to 30. They are easily mountable with a 5-pin DIP package for easy installation. The optocouplers are safety approved and compliant with UL and VDE standards.
