MC10E122FNR2

Overview

The MC10E122FNR2 is a 9-bit non-inverting buffer manufactured by onsemi, belonging to the ECLinPS family. It operates in PECL mode with VCC ranging from 4.2 V to 5.7 V and VEE at 0 V, or in NECL mode with VCC at 0 V and VEE from −4.2 V to −5.7 V. The device features a maximum propagation delay of 500 ps and supports a maximum toggle frequency of 800 MHz. It contains nine internal gates with a transistor count of 111 devices. Packaged in a 28-lead PLCC (FN suffix), it includes internal input 50 kΩ pulldown resistors and provides ESD protection exceeding 2 kV via Human Body Model standards.

Feature Summary

• Contains nine non-inverting buffer gates for high-speed signal buffering
• Supports dual-mode operation in both PECL and NECL configurations
• Includes internal 50 kΩ input pulldown resistors for stable logic levels
• Provides robust ESD protection compliant with Human Body Model standards

Applications

• High-speed digital data buffering in communication systems
• Clock distribution networks requiring low skew and fast propagation
• Interfacing between different voltage level domains using PECL/NECL standards

Procurement Notes

Verify the specific ordering suffix to confirm package type and lead-free status. The 'R2' suffix indicates tape and reel packaging containing 500 units per reel. Confirm RoHS compliance requirements against the 'G' suffix designation if lead-free materials are mandatory for the assembly process. Ensure supply chain availability as component lifecycles may change.

Selection Notes

Select this component when designing circuits requiring nine buffered outputs with minimal propagation delay. It is suitable for applications demanding operation within standard ECL power supply ranges. Consider the thermal resistance characteristics and airflow requirements for maintaining performance at maximum toggle frequencies. Verify that the 28-lead PLCC package fits the available PCB footprint constraints.

Part Context

This part belongs to the MC10E/100E series of ECL logic devices produced by onsemi. The 10E series typically lacks temperature compensation found in the 100E variant, though both share similar functional architectures. These devices are designed for high-frequency applications where signal integrity and speed are critical parameters for system performance.

Replacement Considerations
