The H11L1 and H11L2 have a gallium arsenide IRED optically coupled to a high–speed integrated detector with Schmitt trigger output. Designed for applications requiring electrical isolation, fast response time, noise immunity and digital logic compatibility.

• Guaranteed Switching Times — ton, toff < 4 µs
• Built–In On/Off Threshold Hysteresis
• High Data Rate, 1 MHz Typical (NRZ)
• Wide Supply Voltage Capability
• Microprocessor Compatible Drive
• To order devices that are tested and marked per VDE 0884 requirements, the
   suffix ”V” must be included at end of part number. VDE 0884 is a test option.

Applications
• Interfacing Computer Terminals to Peripheral Equipment
• Digital Control of Power Supplies
• Line Receiver — Eliminates Noise
• Digital Control of Motors and Other Servo Machine Applications
• Logic to Logic Isolator
• Logic Level Shifter — Couples TTL to CMOS
