ON Semiconductor H11L1M 6-Pin DIP Optocoupler, Schmitt Trigger, 7.5kV, 1Mbps

The ON Semiconductor H11L1M is a high-speed, through-hole optocoupler presented in a standard 6-pin DIP package. This device integrates a gallium arsenide infrared emitting diode optically coupled to a high-speed integrated circuit detector with a Schmitt trigger output. The built-in Schmitt trigger provides essential hysteresis for excellent noise immunity and pulse shaping, ensuring clean and reliable digital signals even in electrically noisy environments.

Key to its operation is the optimised detector design, which simplifies integration and enhances performance. This optocoupler is UL 1577 and DIN-EN IEC60747-5-5 certified, guaranteeing high isolation safety standards. It offers a very high typical data rate of 1MHz (NRZ), making it fully compatible with microprocessor drives and suitable for demanding digital isolation applications.

Typical Applications

This versatile component is designed for a wide range of electronic isolation and signal conditioning tasks. Its primary uses include acting as a logic-to-logic isolator to break ground loops and prevent noise propagation between circuit sections. It is also ideal for use in programmable current level sensors, line receivers to eliminate noise and transient issues, and for AC to TTL conversion with square wave shaping. Additionally, it finds application in the digital programming of switch-mode power supplies and as a reliable interface for computer peripherals.
