MC10E171FNR2G

Overview

The MC10E171FNR2G is a 5V/EnECL 3-Bit 4:1 Multiplexer manufactured by onsemi. It contains three independent multiplexers with differential outputs and separate select controls for the leading 2:1 MUX pairs. The device operates in PECL mode (VCC = 4.2 V to 5.5 V, VEE = 0 V) or NECL mode (VCC = 0 V, VEE = −4.2 V to −5.5 V). Key electrical parameters include a maximum propagation delay of 650 ps from data input to output, a typical maximum toggle frequency of 1400 MHz, and a power supply current of 67 mA at 25°C. It features internal 50 kΩ input pulldown resistors and meets JEDEC latchup specifications.

Feature Summary

• Provides three independent 4:1 multiplexers with split select control architecture for the leading stages.
• Features differential true and inverted outputs suitable for high-speed ECL signaling environments.
• Includes internal 50 kΩ input pulldown resistors to manage floating input states.
• Offers robust electrostatic discharge protection exceeding 2 kV via Human Body Model standards.

Applications

• High-speed digital signal routing and switching systems
• Data acquisition and processing circuits requiring low latency selection
• Telecommunications infrastructure utilizing ECL logic families

Procurement Notes

Verify the specific ordering suffix 'FNR2G' corresponds to the PLCC-28 package in tape and reel configuration containing 500 units per reel. Confirm that the Pb-Free designation aligns with project environmental compliance requirements. Ensure the component status is reviewed against current lifecycle management policies as availability may vary.

Selection Notes

Select this component when designing systems requiring three parallel 4:1 multiplexing functions within a single integrated circuit. The choice depends on compatibility with existing PECL or NECL power domains and voltage levels. Evaluate the PLCC-28 footprint constraints against available board space and thermal dissipation capabilities for the target application environment.

Part Context

This device belongs to the MC10E/100E series of ECLinPS logic components produced by onsemi. The '10E' designation indicates standard performance characteristics, while the '100E' variant includes temperature compensation. The MC10E171 specifically addresses applications needing multiple multiplexed channels with differential signaling capabilities.

Replacement Considerations

The MC100E171 serves as a functional equivalent within the same family, distinguished by the inclusion of temperature compensation features. Designers should verify if thermal stability adjustments are necessary before substituting between the 10E and 100E variants.

FAQ

How does the split select architecture function?

The device utilizes separate select inputs where SEL2 controls the final stage selection between two 2:1 MUX pairs, while SEL1A and SEL1B independently control the selection within each pair.

What is the purpose of the internal pulldown resistors?

Internal 50 kΩ pulldown resistors are integrated into the data inputs to ensure defined logic states when inputs are left unconnected or floating, enhancing system reliability.
