MOC8102 is a dual optocoupler integrated circuit (IC) manufactured by Fairchild Semiconductor. It is a 4-pin optocoupler IC with an open collector output. Description: The MOC8102 is a dual optocoupler IC with an open collector output. It has two channels, each with an LED and a phototransistor. The LED is used to transmit the signal, while the phototransistor is used to receive the signal. The output of the phototransistor is an open collector, meaning that the collector is not connected to any voltage source. Features: Low input current High isolation voltage High common mode rejection ratio Low output saturation voltage High temperature range Applications: The MOC8102 is commonly used in applications such as motor control, power supplies, and industrial automation. It can also be used in applications where high isolation voltage and high common mode rejection ratio are required.(For reference only)
