The CT817B(SL)(T3)-H Optocoupler SOP-4 RoHS manufactured by CT Micro International is an opto-coupler type integrated circuit which is packaged in a surface mount SOP-4 configuration. This device contains a gallium arsenide infrared-emitting diode (GaAIr) optically coupled to an integrated detector providing a high level of isolation between the input and output. It offers high-quality electrical insulation performance, featuring low forward resistance, low output saturation and good common-mode noises, as well as compact size and lightweight. The RoHS compliant version ensures operation under lead-free conditions and its wide temperature range of -40? to +85? makes it suitable for a variety of applications, such as data-converter, safety equipment, electronics toys, industrial control, and power supply applications.
