LTV-247

The LTV-247 from Lite-On is a compact, high-performance optocoupler designed for various applications requiring electrical isolation between circuits. This device features a dual-channel configuration, which allows it to transmit signals while maintaining a high degree of isolation, making it ideal for use in communication systems, power supplies, and industrial automation.

The LTV-247 consists of a gallium arsenide (GaAs) infrared LED and a phototransistor housed in a 4-pin DIP (Dual In-line Package) form factor. The LED emits infrared light when an electrical current passes through it, while the phototransistor detects this light and converts it back into an electrical signal. This optical coupling mechanism ensures that the input and output circuits are electrically isolated, providing protection against voltage spikes and noise.

Key specifications of the LTV-247 include a high isolation voltage, typically rated at 5,000 Vrms, which ensures safe operation in high-voltage environments. The device also boasts a fast switching speed, with a rise time of around 5 microseconds and a fall time of approximately 5 microseconds, making it suitable for high-speed data transmission applications.

The LTV-247 is designed to operate over a wide temperature range, typically from -40°C to +100°C, ensuring reliability in various environmental conditions. Its low input current requirement and high current transfer ratio (CTR) make it efficient and effective for signal transmission.

In terms of pin configuration, the LTV-247 features two input pins for the LED and two output pins for the phototransistor. The device is designed for easy integration into circuit boards, allowing for straightforward implementation in both new designs and existing systems.

Overall, the LTV-247 from Lite-On is a versatile and reliable optocoupler that provides essential electrical isolation and signal transmission capabilities, making it a popular choice among engineers and designers in the electronics industry.
