Overview
The AM6687/BEA is a dual-channel, general-purpose voltage comparator manufactured by Advanced Micro Devices. It features an open-emitter ECL output structure and operates within the Linear IC category. Key electrical specifications include a typical propagation delay of 2.7 ns, peak bias input current of 15µA, typical output amperage of 30mA, and maximum idle current of 32mA. The device provides high noise immunity with typical rejection ratios of 80dB CMRR and 60dB PSRR. It is housed in a 16-CDIP package.
Feature Summary
- Ultra-fast switching performance with typical propagation delay of 2.7 ns
- Open-emitter ECL output structure for direct interface compatibility
- High common-mode and power supply rejection ratios for signal integrity
Applications
- High-speed digital logic interfacing
- Voltage monitoring circuits requiring fast response times
- ECL-based system design applications
Procurement Notes
Verify RoHS compliance status as sources indicate non-compliance. Confirm lifecycle status is active before procurement. Ensure the 16-CDIP package variant matches the specific suffix requirements for your assembly process. Cross-reference manufacturer documentation to validate the exact pinout and electrical limits for the BEA suffix configuration.
Selection Notes
Select this component when ultra-fast propagation delay is critical for system timing. The open-emitter ECL output requires appropriate termination and biasing networks. Consider the 15µA peak bias input current for low-power input stage designs. Verify that the 30mA output capability meets the load requirements of the subsequent ECL logic stages without excessive voltage drop.
Part Context
Advanced Micro Devices produces this comparator as part of its linear integrated circuit portfolio. The AM6687 series is distinguished by its speed and ECL compatibility. This specific part serves as a standard general-purpose solution for applications demanding rapid voltage threshold detection in high-frequency environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult manufacturer cross-reference guides for compatible alternatives.
