H11L4

Logic Output Optoisolators Overview

The H11L4 is a logic output optoisolator manufactured by Isocom Components 2004 LTD. It features a single channel with tri-state output capability and provides 5300Vrms isolation voltage. The device supports a data rate of 1MHz and operates within a supply voltage range of 3–15V. It is available in a 6-DIP package.

Logic Output Optoisolators Feature Summary

• Tri-state output configuration for flexible interfacing
• High-speed 1MHz data rate capability
• Robust 5300Vrms isolation barrier

Logic Output Optoisolators Applications

• Digital signal isolation in microcontroller systems
• Logic interface circuits requiring high noise immunity
• Industrial control systems with isolated I/O channels

Logic Output Optoisolators Procurement Notes

Verify the manufacturer designation, as Isocom Components often distributes onsemi products. Confirm the specific suffix indicates the correct package type (DIP vs SMD) and temperature grade. Ensure the part number matches the required tri-state logic output specification rather than standard transistor or open-collector variants.

Logic Output Optoisolators Selection Notes

Select this component when a tri-state output is required for bus sharing or high-speed digital isolation. The 1MHz speed suits moderate-frequency digital communication. Verify that the 5300Vrms isolation meets system safety requirements. Compare against similar logic isolators if higher speed or different packaging is needed.

Logic Output Optoisolators Part Context

This part belongs to the H11L series of logic output optoisolators. It is functionally equivalent to other industry-standard tri-state logic isolators. The H11L4 specifically denotes the through-hole DIP variant, while surface mount versions may carry different suffixes like SM or SMT.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include HCPL-2601 or HCPL-2630 from Broadcom/Avago. Other compatible parts are PC900 or IL300 equivalents depending on pinout compatibility. Verify pin assignments and electrical parameters before substitution.
