MC10H158FNG

Overview

The MC10H158FNG is a quad two-input multiplexer from the MECL 10H family, housed in a 20-lead PLCC package. It features common input select logic where a high level enables inputs D00, D10, D20, and D30, while a low level enables D01, D11, D21, and D31. The device operates on a single supply voltage ranging from -4.94V to -5.46V. Typical propagation delay is 1.5 ns with typical power dissipation of 197 mW.

Feature Summary

• Functional and pinout duplication of the standard MECL 10K family part
• Provides 100% improvement in propagation delay without increasing power-supply current
• Features voltage compensated design for improved noise margin over operating voltage and temperature range

Applications

• High-speed data routing applications requiring differential ECL signaling
• Signal path selection in telecommunications equipment
• Multiplexing functions in digital communication systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as non-compliant versions exist. Check for lead-free suffixes (G) if required by environmental regulations. Ensure proper handling procedures are followed due to surface mount packaging requirements.

Selection Notes

Select this component when MECL 10K compatibility is required alongside faster switching speeds. Consider the 20-PLCC package constraints for PCB layout. Evaluate thermal management needs given the specified power dissipation characteristics. Verify that the operating temperature range meets system environmental requirements.

Part Context

Part of the MECL 10H series designed for high-speed digital applications. Offers enhanced performance compared to legacy MECL 10K devices while maintaining backward compatibility. Suitable for systems requiring reliable signal multiplexing with minimal propagation delay.

Replacement Considerations

MC10H158FN serves as a direct equivalent within the same package type. MC10H158P provides identical functionality in a PDIP-16 package. Cross-reference datasheet specifications before substitution to ensure electrical parameter alignment.
