Optocouplers, like the 6n138, are used for electrical isolation. This means they transfer signals between circuits without a direct electrical connection. This is particularly important in situations where voltage differences are significant or where ground loops might cause interference. The 6n138 datasheet outlines the device’s ability to withstand high voltages between its input and output sides. This capability is usually indicated using the term “Isolation Voltage”. These devices are common in applications requiring enhanced safety and noise immunity. Here are few characteristics found inside the datasheet:
- CTR (Current Transfer Ratio): The ratio of output current to input current.
- Propagation Delay: How long it takes for a signal to propagate through the optocoupler.
- Isolation Voltage: The maximum voltage the device can withstand between input and output.
Here’s a simple table to illustrate a typical use case for the 6n138, and how the datasheet is important:
| Application | Reason for using 6n138 | Datasheet’s Role |
|---|---|---|
