MC10H158FNR2G

Overview

The MC10H158FNR2G is a quad two-channel multiplexer with common input select, belonging to the MECL 10H logic family. It operates on a single supply voltage ranging from -4.94 V to -5.46 V. The device features a typical propagation delay of 1.5 ns and power dissipation of 197 mW. It utilizes a 20-PLCC package with J-leads and supports an operating temperature range of 0°C to +75°C.

Feature Summary

• Provides four independent two-to-one multiplexing channels controlled by a single common select line.
• Features improved noise margin of 150 mV over the full operating voltage and temperature range.
• Offers functional and pinout compatibility with the standard MECL 10K family while delivering faster propagation delays.

Applications

• High-speed data routing in telecommunications systems
• Signal selection in test and measurement equipment
• Multiplexing applications requiring MECL 10K compatibility

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type and environmental compliance status. Review the latest datasheet revision for any updates to electrical characteristics or mechanical dimensions prior to finalizing procurement specifications.

Selection Notes

Select this component when high-speed signal switching is required within the MECL logic ecosystem. Ensure the design accommodates the negative supply voltage requirements and differential signaling characteristics inherent to the MECL 10H family. Verify that the thermal management strategy addresses the specified power dissipation levels under maximum load conditions.

Part Context

This part belongs to the MC10H158 series, which includes variants such as the MC10H158FN and MC10H158FNR2. The 'G' suffix indicates a lead-free package compliant with RoHS standards. The device serves as a high-performance alternative to legacy MECL 10K multiplexers, offering enhanced speed without increasing power consumption.

Replacement Considerations

The MC10H158 is functionally compatible with standard MECL 10K family parts. Designers should verify that replacement components maintain the same pinout configuration and electrical interface requirements to ensure seamless integration into existing circuits.
