MC10E122FNG

Overview

The MC10E122FNG is a 9-bit non-inverting buffer from the onsemi MC10E/100E122 series, designed for high-speed digital signal processing. It operates in PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) and NECL mode with VEE ranging from -4.2 V to -5.7 V (VCC = 0 V). The device features a maximum propagation delay of 500 ps and a maximum toggle frequency of 800 MHz. It contains nine differential ECL data inputs (D0-D8) and outputs (Q0-Q8), housed in a 28-lead PLCC package.

Feature Summary

• Contains nine non-inverting buffer gates for parallel signal buffering
• Supports both PECL and NECL logic families for flexible power supply configurations
• Includes internal input pulldown resistors to manage floating input states
• Provides enhanced electrostatic discharge protection exceeding standard thresholds

Applications

• High-speed clock distribution networks
• Parallel data bus buffering systems
• Telecommunications equipment requiring low skew timing
• Test and measurement instrumentation interfaces

Procurement Notes

Verify the specific suffix 'FN' or 'FNG' against the datasheet ordering information to confirm the lead-free status and packaging type. Confirm that the required quantity matches the rail or tape-and-reel specifications provided by the manufacturer. Ensure compatibility with the 28-lead PLCC footprint during procurement planning.

Selection Notes

Select this component when a high-density, multi-channel non-inverting buffer is required for ECL-based architectures. Consider the MC100E122 variant if temperature compensation is necessary for stable performance across varying thermal conditions. Evaluate the 800 MHz toggle frequency limit to ensure it meets the system's maximum clock requirements.

Part Context

This part belongs to the MC10E/ECLinPS family of high-speed logic devices manufactured by onsemi. These components are engineered for demanding applications where signal integrity and precise timing are critical. The MC10E122 specifically addresses the need for buffering multiple data lines simultaneously within a single integrated circuit package.

Replacement Considerations

The MC100E122 serves as a functional equivalent within the same family, distinguished primarily by its inclusion of temperature compensation features. Verify pinout compatibility and electrical characteristics before substituting between the 10E and 100E series variants.
