LTV-814S-TA1

The LTV-814S-TA1 is an optocoupler (also known as an opto-isolator) manufactured by Lite-On, designed to provide electrical isolation between its input and output while allowing signal transmission. This component is particularly useful in applications where it is necessary to separate different parts of a circuit to prevent high voltages from affecting sensitive components.

Key Features:

1. Isolation Voltage: The LTV-814S-TA1 typically offers a high isolation voltage, often around 5,000 Vrms, which ensures that the input and output sides are electrically isolated, providing safety and protection for sensitive devices.

2. Input Configuration: The input side of the optocoupler consists of an infrared LED. When a current flows through the LED, it emits infrared light. The forward voltage drop across the LED is usually around 1.2V, and it can handle a forward current of up to 20 mA.

3. Output Configuration: The output side features a phototransistor that is sensitive to the infrared light emitted by the LED. When the LED is activated, the phototransistor conducts, allowing current to flow through the output circuit. The output can typically handle a collector-emitter voltage of up to 50V and a collector current of around 50 mA.

4. Transfer Characteristics: The LTV-814S-TA1 has a high current transfer ratio (CTR), which indicates the efficiency of the optocoupler in transferring the input signal to the output. The CTR can vary, but it is generally in the range of 100% to 600%, depending on the specific conditions.

5. Package Type: The device is housed in a compact 4-pin DIP (Dual In-line Package) form factor, making it suitable for PCB mounting and allowing for easy integration into various electronic circuits.

6. Temperature Range: The operating temperature range for the LTV-814S-TA1 is typically from -40°C to +85°C, making it suitable for a wide range of applications, including industrial and consumer electronics.

7. Applications: This optocoupler is commonly used in applications such as signal isolation, data communication, power supply feedback, and interfacing between different voltage levels in electronic systems.

Summary:

The LTV-814S-TA1 from Lite-On is a reliable and efficient optocoupler that provides electrical isolation and signal transmission capabilities. Its robust design, high isolation voltage, and versatile applications make it a popular choice for engineers and designers looking to enhance the safety and performance of their electronic circuits.
