IS900G

Logic Output Optoisolators Overview

The IS900G is a microprocessor-compatible Schmitt trigger optically coupled isolator manufactured by Isocom Components. It features a single channel with tri-state logic output and operates at frequencies up to 1MHz. The device provides high common-mode transient immunity and utilizes a 6-DIP package for through-hole mounting. Key electrical specifications include a minimum isolation voltage of 5000Vrms, ensuring robust signal transmission across isolated domains while maintaining compatibility with standard digital logic interfaces.

Logic Output Optoisolators Feature Summary

• Integrates Schmitt trigger input for noise-immune signal conditioning
• Provides tri-state logic output for flexible bus interfacing
• Ensures high common-mode transient immunity for reliable operation in noisy environments

Logic Output Optoisolators Applications

• Microprocessor system isolation
• Digital communication interface isolation
• Signal transmission between isolated logic domains

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'G' against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure the component status remains active for long-term supply stability. Cross-reference the isolation voltage rating with system safety requirements before integration.

Logic Output Optoisolators Selection Notes

Select this component when tri-state output capability is required for shared bus architectures. The high CMTI makes it suitable for applications with significant ground potential differences. Verify that the 1MHz speed meets the data rate requirements of the target application.

Logic Output Optoisolators Part Context

This part belongs to the family of Schmitt trigger optocouplers designed for digital isolation. It replaces older transistor-output couplers where faster switching and noise immunity were critical. The device bridges the gap between simple phototransistors and complex gate arrays in mid-speed digital systems.

Logic Output Optoisolators Replacement Considerations

Check for direct substitutes such as the IS900 variant if the 'G' suffix denotes a specific package or lead-free compliance change. Verify pin compatibility before swapping with other Schmitt trigger optocouplers from different manufacturers.
