Optoisolators are a type of electronic component with many applications, and the HCPL-260L-300E is an example of such a part. It is one which features a logic output, specifically a 10V) LVTTL gate drive. Logic output optoisolators are well-suited for providing protection between components in a digital system. This article will explain the application field and working principle of the HCPL-260L-300E.

Application Field

The HCPL-260L-300E is classed as an optocoupler and the application field of this type of device is primarily that of isolating the inputs and outputs of two systems from each other. This electronic component achieves solidarity through the use of an LED light source and a photodetector. Signals can be transmitted without the input/output isolation, protecting the device from any changes in the other system.

Current-mode logic (CML) output optoisolators are particularly suited for providing galvanic isolation in high-speed digital circuits. The HCPL-260L-300E is one such isolated driver which provides fan-out using logic-compatible 10V) LVTTL levels. It is able to handle speeds of up to 250 Mbps.

There are a range of applications for which the HCPL-260L-300E is suited. One example is as an isolated driver in FPGA designs for data transmission. The high-speed data transfers achievable with this part make it suitable for this as well as numerous other applications. Its status as an LVTTL-compatible output also adds to its versatility when giving digital isolation.

Working Principle

The HCPL-260L-300E is a current-mode logic (CML) optoisolator, as explained previously. This type of optoisolator works by using an LED light source which is connected to the input system, and a photodetector which is connected to the output system. The LED is activated through the input system in the form of a logic signal. This causes the LED to emit light which is then detected by the photodetector on the output system. This process is completely isolated, providing a more secure connection.

The HCPL-260L-300E has an additional feature which is pertinent to its working principle. This is the gate drive, which is a 10V) LVTTL level. This feature provides a means of protection between the two systems, as it increases the speed of the transmission without risk of a different signal being misinterpreted. Additionally, the isolator is able to handle speeds of up to 250 Mbps, making it ideal for applications such as FPGA data transmission.

The working principle of the HCPL-260L-300E is based on the use of LED light pass-through from an isolated input to an isolated output. This allows data to travel between the two systems without the risk of any data loss due to interference. The 10V) LVTTL gate drive increases transmission speed and ensures that the data is accurately interpreted by the receiving system.

Conclusion

The HCPL-260L-300E is a current-mode logic (CML) optoisolator providing a logic-compatible 10V) LVTTL gate drive. It is best suited for fast data transmission in applications such as FPGAs and is capable of speeds up to 250 Mbps. Its application field revolves around providing isolated inputs and outputs for digital systems, which can be accomplished through its LED light source and photodetector working principle.
