6N137TVM

The 6N137TVM optoisolator is part of the family of Logic Output optoisolators, which are used to provide electrical isolation between two electrical circuits while transferring logic level signals. Commonly used in communications, instrumentation and process control applications, the 6N137TVM optoisolator enables the transfer of digital signals between circuits operating at different voltage levels, while maintaining electrical isolation between the circuits.

Technical Specifications

• Operating Voltage : 5.0 Vdc (Max)
• I/O Current : Max 20 mA

• Isolation Voltage : 500 Vdc min

The 6N137TVM optoisolator is a three terminal device that contains one LED and one photo-transistor internally connected. It is highly reliable and easily mounted in standard DIP socket. In operation, the LED is driven by an input signal, typically 7.0 Vdc or more, applied to the "Input" terminal of the optoisolator. When the LED is turned on, a current flows through the LED and an output voltage is generated across the phototransistor. The output from the 6N137TVM optoisolator can be used to drive a variety of logic circuits, In addition, because of the high isolation voltage, the 6N137TVM optoisolator can also be used to separate TTL systems.

The 6N137TVM optoisolator is ideal for applications that require electrical isolation and logic level control of other circuits. Common applications include: control and monitoring of process control and instrumentation signals, Power ID and process control, communications, high voltage circuit isolation and logic level conversion.

Conclusion

The 6N137TVM optoisolator is a specially designed three terminal device containing one LED and one phototransistor that provides electrical and optical isolation between circuits. It is particularly useful for controlling and monitoring process control and instrumentation signals, power ID and process control, communications, and applications that require electrical isolation and logic level conversion.
