ON Semiconductor H11L1S Optoisolator

The H11L1S from ON Semiconductor is a robust optoelectronic device designed to provide signal isolation with high data rate capabilities. This product is part of the H11Lx series, which are known for their high-speed logic gate optocouplers. The H11L1S specifically offers an ideal solution for applications requiring isolation in noisy environments, where signal integrity and isolation are of paramount importance.

The H11L1S optoisolator consists of a gallium arsenide infrared LED and a microprocessor-compatible Schmitt trigger output, which allows for easy interfacing with digital circuits. The device is capable of transmitting data at rates up to 1 MBd, making it suitable for a wide range of applications, including telecommunication, computer peripheral interfaces, microprocessor system interfaces, digital isolation for A/D, D/A conversion, and many others.

With its high isolation voltage of 7500V peak, the H11L1S ensures that the input and output are electrically isolated, which is critical in protecting sensitive electronic components from high voltage spikes and surges. Additionally, the optoisolator provides a minimum Common Mode Rejection (CMR) of 5 kV/μs at a VCM of 1000V, which is excellent for rejecting high-voltage transients on the bus lines.

The H11L1S comes in a compact 6-pin DIP package, making it easy to integrate into various circuit designs. It is also available in a surface-mountable SOIC-6 package for space-constrained applications. The device is UL recognized and approved under the Component Recognition Program of Underwriters Laboratories, ensuring its safety and reliability in end-use applications.

ON Semiconductor's commitment to quality is evident in the H11L1S optoisolator, which is manufactured to meet the strict standards of the industry. With its combination of high-speed performance, electrical isolation, and compatibility with digital logic levels, the H11L1S is an excellent choice for designers seeking to enhance the performance and reliability of their electronic systems.
