H11L1

Logic Output Optoisolators Overview

The H11L1 is a microprocessor-compatible Schmitt Trigger Optically Coupled Isolator manufactured by Isocom Components. It integrates a gallium arsenide infrared emitting diode with a logic output stage. The device features an open collector output and provides 5000Vrms isolation voltage. It operates within a temperature range of -55°C to 100°C. Typical rise and fall times are 0.1μs, supporting high-speed digital signal transmission. The component is available in a 6-pin DIP package and complies with RoHS, UL, and VDE standards.

Logic Output Optoisolators Feature Summary

Logic Output Optoisolators Applications

• Microprocessor system interfacing
• Digital signal isolation
• Logic level translation between isolated circuits
• High-speed data transmission channels

Logic Output Optoisolators Procurement Notes

Verify the specific manufacturer designation, as Isocom Components may be associated with 2004 LTD or other entities depending on the source. Confirm the package type matches the required application, as variations such as surface mount versions exist within the broader H11L1 family. Ensure compliance requirements align with project specifications before ordering.

Logic Output Optoisolators Selection Notes

Select this component when Schmitt Trigger input hysteresis is required to prevent false triggering from noisy signals. The open collector output necessitates an external pull-up resistor for proper logic high levels. Consider the operating temperature range if the environment exceeds standard commercial limits. Verify pinout compatibility with existing PCB footprints.

Logic Output Optoisolators Part Context

The H11L1 belongs to the H11L1 series of optocouplers designed for robust digital isolation. It differs from transistor-output variants by providing clean logic transitions suitable for microprocessors. Similar models include the H11L1SM for surface mount applications. The device is distinct from AC-input optocouplers like the H11AV1SM.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include the 6N137S from Lite-On Inc., which offers similar isolation and speed characteristics. Other compatible options may exist within the same manufacturer's portfolio or from alternative suppliers offering equivalent Schmitt Trigger optocouplers.
