MC10E171FN

Overview

The MC10E171FN is a 5V ECL 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) or NECL mode (VCC = 0 V, VEE = −4.2 V to −5.5 V). Maximum data-to-output propagation delay is 650 ps at 85°C, with a maximum toggle frequency of 1400 MHz. Internal input pulldown resistors are 50 kΩ.

Feature Summary

• Provides split select control architecture for efficient signal routing within the multiplexer structure.
• Features internal 50 kΩ input pulldown resistors to manage input states without external components.
• Includes robust electrostatic discharge protection exceeding 2 kV human body model and 200 V machine model standards.
• Offers differential true and inverted outputs suitable for high-speed logic applications.

Applications

• High-speed digital signal routing systems
• Data acquisition and switching circuits
• Communication equipment requiring fast multiplexing

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and environmental compliance. Confirm that all power supply pins are correctly connected to ensure proper operation. Check for any recent product change notices or discontinuation announcements before finalizing procurement plans.

Selection Notes

Select this component when a 3-channel 4:1 multiplexer with differential outputs is required. Ensure the design supports either PECL or NECL voltage levels. Verify that the PCB layout accommodates the PLCC-28 package dimensions and thermal requirements for the intended operating temperature range.

Part Context

This part belongs to the MC10E/100E series of ECL logic devices manufactured by onsemi. The '10' prefix indicates standard performance, while '100' denotes temperature-compensated variants. The FN suffix specifies the 28-lead Plastic Leadless Chip Carrier package.

Replacement Considerations

MC100E171FN serves as the temperature-compensated equivalent within the same family. Other parts in the 10E series may offer similar functionality but require verification of pin compatibility and electrical specifications.

FAQ

What is the function of the split select inputs?

The split select inputs allow separate control over the leading 2:1 MUX pairs within each 4:1 multiplexer channel, providing flexible routing options.

How does the device handle input states when not actively driven?

The device includes internal 50 kΩ pulldown resistors on the inputs, which help define the state of unconnected or floating input pins.
