6N134/883B

Overview

The Broadcom Limited 6N134/883B is a high-reliability, Class H, dual-channel hermetically sealed optocoupler housed in a 16-pin ceramic DIP package. It features gold-plated and solder-dipped leads for robust connectivity. The device integrates an infrared LED input with photodiode and signal processing circuitry to deliver logic output via open-collector configurations. Key electrical specifications include a data rate of 10 Mb/s, an isolation voltage of 2500 Vrms (or 1500 Vdc), and a current transfer ratio of 100%. It provides a common-mode transient immunity of 1 kV/µs and operates within standard commercial temperature ranges.

Feature Summary

• Hermetically sealed construction in a 16-pin ceramic DIP package ensures high reliability and environmental protection.
• Dual-channel design with open-collector outputs facilitates direct interfacing with digital logic circuits.
• High-speed performance supports data rates up to 10 Mb/s with significant common-mode transient immunity.

Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial control systems demanding reliable signal transmission across isolated domains
• Microprocessor-based systems needing protected I/O channels

Procurement Notes

Verify the specific ordering suffix, such as #200, to confirm reel packaging or tape-and-reel availability if required for automated assembly processes. Ensure the selected variant matches the lead finish requirements, typically gold-plated or solder-dipped, for compatible surface mounting or through-hole integration. Confirm that the 16-pin ceramic DIP form factor aligns with existing PCB footprint constraints and thermal management needs before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation with high-speed logic output is necessary. The 10 Mb/s data rate suits applications requiring rapid signal switching between isolated grounds. Consider the 16-pin ceramic DIP package size for board space limitations. Verify that the open-collector output type meets the pull-up resistor requirements of the destination logic family. Ensure the 2500 Vrms isolation rating satisfies the safety standards of the target application environment.

Part Context

This part belongs to Broadcom's series of high-speed logic output optoisolators. It shares architectural similarities with other models in the family but distinguishes itself through its dual-channel configuration and hermetic sealing. The 6N134/883B serves as a specialized solution for environments where standard plastic-packaged optocouplers may lack sufficient durability or isolation performance.

Replacement Considerations

Direct substitutes must match the 16-pin ceramic DIP package, dual-channel architecture, and 10 Mb/s speed. Verify equivalent isolation voltages and open-collector output types. Cross-reference pinouts to ensure compatibility without redesigning the host circuit board.
