MC10E158FN

Overview

The MC10E158FN is a 5V ECL quad 2:1 multiplexer manufactured by onsemi. It integrates four independent multiplexing circuits within a single package, providing high-speed signal routing capabilities for differential logic applications. The device operates with a supply voltage range of -4.2V to -5.7V and functions reliably across an operating temperature range of 0°C to 75°C. It is housed in a 28-lead PLCC surface-mount package designed for efficient board space utilization.

Feature Summary

• Integrates four independent 2:1 multiplexing channels for parallel data selection
• Optimized for high-speed differential ECL signal processing
• Surface-mount packaging facilitates automated assembly processes

Applications

• High-speed digital signal routing systems
• Differential data bus switching architectures
• Telecommunications equipment requiring fast signal path selection

Procurement Notes

Verify the specific suffix 'FN' against current manufacturer documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status as older revisions may differ from current production standards. Check for obsolescence notices or lifecycle changes before finalizing procurement plans to ensure long-term supply availability.

Selection Notes

Select this component when designing systems requiring multiple independent 2:1 signal paths within a single integrated circuit. Ensure the design supports standard 5V ECL power rails and differential signaling requirements. Consider the 28-lead PLCC footprint constraints during PCB layout planning to match the physical dimensions specified in the official datasheet.

Part Context

This part belongs to the MC10E series of 5V ECL logic devices, which are engineered for high-frequency performance. The MC10E158 specifically addresses applications needing multiple multiplexer functions without consuming excessive board area compared to discrete solutions.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the MC10EL58 or MC100EL58, noting that these variants may offer improved propagation delays or temperature compensation features not present in the base MC10E model.
