It features open collector outputs and supports a data rate of 10 Mb/s with a forward current of 20 mA and forward voltage of 1.5 V. The device provides 2500 VDC isolation and offers a common-mode transient immunity of 1 kV/µs. Operating temperatures range from -55°C to +125°C, with rise and fall times of 90 ns and 40 ns respectively.

Feature Summary

• Hermetically sealed construction for enhanced reliability
• High common-mode transient immunity capability
• TTL-compatible logic output configuration

Applications

• Military and aerospace systems requiring hermetic sealing
• High-speed digital signal isolation interfaces
• Industrial control systems demanding high CMR

Procurement Notes

Verify the specific suffix against official datasheets to confirm isolation voltage ratings and pinout configurations. Ensure compatibility with MIL-PRF-38534 standards if military-grade performance is required. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when hermetic sealing and high-speed operation are critical requirements. The dual-channel design simplifies board layout for isolated bidirectional communication. Verify that the open-collector output interface matches the receiving circuit's input impedance and voltage levels.

Part Context

This part belongs to the 81028 series of high-speed, high-CMR logic gate optocouplers. These devices are designed for applications requiring robust signal transmission across isolated barriers while maintaining fast switching speeds and high noise immunity in electrically noisy environments.

Replacement Considerations

Consult official substitution matrices for compatible alternatives within the same hermetic family. Verify equivalent isolation voltages and data rates when considering cross-references.
