The LTV-214-G is a dual-channel phototransistor optocoupler from Lite-On Inc. It consists of two gallium arsenide infrared emitting diodes optically coupled to two silicon phototransistors. This configuration provides high isolation voltage and current transfer ratio, making it suitable for various isolation and control applications.

Applications

• Industrial control equipment: Used for isolating control signals between different parts of the system.
• Power supplies: Provides isolation between the primary and secondary sides of power supplies.
• Signal transmission between systems of different potentials: Prevents ground loops and protects sensitive circuitry.
• Digital logic input isolation: Isolates digital inputs from noise and high voltages.
• Motor control: Used in motor control circuits for isolating control signals to the motor drive circuitry.

Features

• Dual-channel configuration: Two optocouplers in a single package.
• High isolation voltage: Provides electrical isolation between input and output.
• High current transfer ratio (CTR): Enables efficient signal transfer.
• Compact package: Saves space on the circuit board.
• RoHS compliant: Environmentally friendly.
• Operating temperature range: Suitable for use in a variety of environments.

Benefits

• Enhanced safety: Protects users and equipment from high voltages.
• Improved noise immunity: Reduces the effects of electrical noise on signal transmission.
• Simplified circuit design: Reduces the number of components required for isolation.
• Increased reliability: Provides a robust and reliable isolation solution.
• Reduced size and cost: Dual channel in one package reduces component count and board space compared to using two single-channel devices.

Additional Details

The LTV-214-G features a collector-emitter voltage (VCEO) typically around 80V, allowing it to interface with various voltage levels. The current transfer ratio (CTR) varies depending on the input current and operating conditions, typically specified at several different If test currents. The isolation voltage is a critical parameter, often exceeding several kilovolts. This optocoupler is available in a standard DIP package for easy through-hole mounting.
