MC10E157FNG

Overview

The MC10E157FNG is a 5 V/EnECL Quad 2:1 Multiplexer in a 28-Lead PLCC package. It contains four independent multiplexers with differential outputs controlled by individual Select (SEL) inputs. The device operates in PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = −4.2 V to −5.7 V). Key electrical parameters include a maximum propagation delay of 550 ps from data input to output and 800 ps from select input to output. The maximum toggle frequency is 1100 MHz.

Feature Summary

• Features four independent 2:1 multiplexers with differential ECL outputs for flexible random logic designs.
• Includes internal 50 kΩ input pulldown resistors to simplify circuit design and improve stability.
• Provides robust electrostatic discharge protection exceeding 2 kV for human body model and machine model testing.

Applications

• High-speed digital signal routing
• Random logic circuit implementations
• Data selection in communication systems

Procurement Notes

Verify the specific ordering suffix 'FN' corresponds to the PLCC-28 plastic leaded chip carrier package configuration. Confirm that the 'G' suffix indicates a Pb-Free compliant component. Ensure compatibility with existing PCB footprints for CASE 776-02 packages before finalizing procurement plans.

Selection Notes

Select this component when multiple independent 2:1 multiplexing functions are required within a single integrated circuit. The device supports both PECL and NECL voltage standards, offering flexibility for different power supply architectures. Individual select controls allow for precise, independent channel management across all four multiplexers.

Part Context

This part belongs to the MC10E/100E series of EnECL logic devices manufactured by onsemi. The 100 Series variants typically include temperature compensation features not present in the standard 10 Series. The MC10E157 specifically provides quad 2:1 multiplexing capabilities optimized for high-speed differential signaling applications.

FAQ

Does the MC10E157FNG support temperature compensation?

No, the MC10E157FNG belongs to the 10 Series which does not contain temperature compensation. Temperature compensation is a feature reserved for the 100 Series devices.

What is the function of the NC pins on the MC10E157FNG?

The NC pins indicate No Connect points on the 28-Lead PLCC package. These pins are internally unconnected and should not be tied to any power or ground rails.
