MC10E171FNR2

Overview

The MC10E171FNR2 is a 5V/EnECL 3-Bit 4:1 Multiplexer featuring differential outputs. It contains three independent multiplexers with split select controls for leading 2:1 MUX pairs. The device operates in PECL mode (VCC = 4.2 V to 5.5 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = −4.2 V to −5.5 V). Key electrical parameters include a maximum D-to-output propagation delay of 650 ps and a maximum toggle frequency of 1400 MHz. Internal input pulldown resistors are integrated.

Feature Summary

• Features split select architecture allowing separate control for leading 2:1 MUX pairs within the 4:1 structure.
• Provides differential true and inverted outputs for high-speed signal integrity.
• Includes internal input pulldown resistors to manage undefined states.
• Offers ESD protection exceeding 2 kV Human Body Model and 200 V Machine Model ratings.

Applications

• High-speed data routing in communication systems
• Signal selection in clock distribution networks
• Multiplexing differential data streams in processing units

Procurement Notes

Verify the specific ordering suffix 'FNR2' corresponds to the PLCC-28 tape and reel packaging configuration. Confirm that the component meets RoHS standards if lead-free variants are required for assembly processes. Ensure all power supply pins are properly connected to guarantee operational stability during procurement validation.

Selection Notes

Select this component when differential output signaling is required for three independent 4:1 multiplexing functions. The split select feature allows flexible addressing of data inputs. Verify compatibility with existing PECL or NECL voltage levels and ensure the PCB layout supports the PLCC-28 package dimensions and thermal requirements.

Part Context

This device belongs to the MC10E/100E series of EnECL logic components manufactured by onsemi. The 100 series variant includes temperature compensation, whereas the standard 10 series does not. The FNR2 suffix indicates a specific reel-based packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official manufacturer resources for cross-reference information before replacing this component in existing designs.

FAQ

How does the split select feature function?

The device provides separate Select inputs (SEL1A, SEL1B, and SEL2) that control the leading 2:1 MUX pairs, allowing for hierarchical selection of the four data inputs for each of the three multiplexers.

What is the maximum operating frequency?

The maximum toggle frequency is specified as 1400 MHz under standard operating conditions.
