LITEON Technology LTV-356T-C Environmental and export classification status description

The Lite-On Technology LTV-356T-C is an optocoupler (or opto-isolator) that provides galvanic isolation between its input and output while enabling signals to pass electronically. It employs an infrared emitting diode and a phototransistor in a single package, which allows for the effective isolation of different sections of a circuit. Functions - Signal Isolation: It separates different parts of a circuit to protect sensitive components from high voltages or noise. - Control and Sensing: It can control larger loads by receiving small input signals. - Voltage Level Shifting: The device allows interfacing between circuits operating at different voltage levels. Applications - Industrial Automation: Used in interfacing between microcontrollers and high voltage loads. - Signal Transmission: Employed in data communication applications where isolation is required. - Power Supply Circuits: Often used in switching power supplies to provide feedback while maintaining isolation. Alternative Parts - MOC3063: Another optocoupler with similar features, commonly used in similar applications. - PC817: A popular optocoupler for low-speed applications. - HCPL-2601: Provides isolation suitable for various applications, with higher performance. Embedded Modules While the LTV-356T-C itself is a component, it can often be found in or easily suitable/compatible with various embedded systems and modules like: - Arduino: Can be used for interfacing with high voltage circuits. - Raspberry Pi: Ideal for use when connecting to high-power devices or sensitive sensors. - Microcontroller Boards: Perfect for isolating digital signals in embedded systems.
