H11L4G

Logic Output Optoisolators Overview

The H11L4G is a single-channel logic output optocoupler manufactured by Isocom Components 2004 LTD. It features a Schmitt trigger input and a tri-state output, designed for microprocessor compatibility. The device provides high-speed signal isolation with a typical propagation delay of 0.5 microseconds and a common-mode transient immunity (CMTI) of 5300 V/µs. It operates within a voltage range of 4.5V to 5.5V and supports data rates up to 1 MHz. The component is housed in a standard 6-pin DIP package, offering robust electrical isolation between input and output circuits.

Logic Output Optoisolators Feature Summary

• Integrates a Schmitt trigger on the input side to eliminate noise-induced false triggering and ensure clean digital signal transitions.
• Features a tri-state output configuration that allows multiple devices to share a common bus without electrical interference.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.

Logic Output Optoisolators Applications

• Microprocessor system interface isolation
• Digital communication bus isolation
• Noise-immune signal transmission in industrial control systems

Logic Output Optoisolators Procurement Notes

Verify the specific manufacturer designation and date code upon receipt. Confirm that the received components match the H11L4G part number exactly. Check for physical damage to the DIP package pins. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate authenticity through official distributor channels or authorized supply chains.

Logic Output Optoisolators Selection Notes

Select this component when tri-state output capability is required for bus sharing applications. Consider the 5300 V/µs CMTI rating for high-noise environments. Ensure the operating voltage aligns with the 4.5V to 5.5V specification. Verify that the 1 MHz speed meets the system's timing requirements. Compare pinout compatibility with existing PCB layouts before integration.

Logic Output Optoisolators Part Context

This component belongs to the H11L series of logic output optocouplers from Isocom Components.
