Optoisolators are used in a wide range of application to provide an interface that can prevent direct electrical contact between two circuits. The ACPL-C61L-560E is one such Optoisolator in the Logic Output category, a part of the ACPL-C60L series. This Optoisolator is an isolated transistor output with an input LED that can handle both analog as well as TTL signal levels.

Features

The main feature of the ACPL-C61L-560E is its ability to work in isolation which is enabled by the use of an optocoupler or optical receivers. It provides up to 4,500 Vrms of electrical isolation between the output and input, which helps protect against electrical transients and EMI/RFI noise. Additionally, it has a temperature range of -40 to 125 °C. The ACPL-C61L-560E also features an insulation distance of 4.5 mm and a creepage distance of 6.4 mm. Furthermore, this Optoisolator has a wide supply voltage range of 2.2 to 20 V and very low input current of 2 mA. This is combined with a fast switching time of 25 ns for the low output and a capability to drive up to 32mA load current in Sink both TTL and CMOS compliant.

Applications

The ACPL-C61L-560E Optoisolator can be used in a variety of applications. It is most commonly used for board level isolation, where it can be used to isolate an input signal from a source that has a different signal level than that of the input. For example, it can be used to convert a 3.3 V signal to a 5 V signal without shorting the input. It can also be used in high speed data transmission applications, like isolation of TTL signals, such as RS485. This Optoisolator can also be used in high voltage AC switching circuits where current and voltage need to be isolated, and in medical devices, industrial controllers, and automotive applications.

Working Principle

The ACPL-C61L-560E Optoisolator works on the principle of interruption of light. The device has two parts: the input side contains a light-emitting diode (LED) and the output contains a phototransistor. When a current passes through the LED, it produces a low-intensity light which is then used to activate the phototransistor. When this occurs, the phototransistor will be triggered, producing an output current which can be used to drive a relay, sensor, or other device. The isolation between the input and the output is ensured by the fact that only light is exchanged between the two sides and no electrical connection is required.

Conclusion

The ACPL-C61L-560E Optoisolator can be used in a wide range of applications, where it can provide electrical isolation without sacrificing performance and reliability. Thanks to features like its wide temperature range, fast switching time, high isolation voltage, and low input current, this Optoisolator is suitable for even the most demanding applications.
