MC10E158FNR2G

Overview

The MC10E158FNR2G is a 5 V ECL 5-bit 2:1 multiplexer manufactured by onsemi. It operates within a supply voltage range of 4.2 V to 5.7 V and supports clock frequencies up to 1100 MHz. The device features a propagation delay of 0.7 ns at 5 V and provides high output currents of 50 mA for both high and low logic states. Packaged in a 28-lead PLCC, it integrates dual circuits suitable for high-speed data selection applications.

Feature Summary

• Integrates five independent 2:1 multiplexing channels within a single package
• Supports differential ECL signaling with high drive capability
• Optimized for high-frequency operation with minimal signal propagation delay

Applications

• High-speed digital data routing systems
• Clock distribution networks requiring fast switching
• Telecommunications equipment signal processing

Procurement Notes

Verify the specific suffix FNR2G against the manufacturer datasheet to confirm tape-and-reel packaging and lead-free compliance. Ensure the design accommodates the required 5V ECL power supply rails and termination resistors. Confirm that the 28-lead PLCC footprint matches the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring multiple parallel 2:1 data paths with strict timing constraints. The ECL technology ensures superior speed compared to TTL or CMOS alternatives. Verify that the system power budget can support the specified current requirements and that thermal management addresses the heat dissipation needs of the PLCC package.

Part Context

This part belongs to the MC10E series of emitter-coupled logic devices designed for high-performance computing and communication infrastructure. The series emphasizes speed and reliability in harsh electrical environments. The MC10E158 specifically addresses the need for compact, multi-channel multiplexing solutions without sacrificing signal integrity at gigahertz rates.

Replacement Considerations

Check for MC10E158FN or MC10E158FNG as potential pin-compatible variants. Verify if the MC10EL58 offers improved performance characteristics for specific temperature ranges. Always consult the latest obsolescence notices to ensure long-term availability.
