MC10E451FN

Flip Flops Overview

The MC10E451FN is a high-speed ECL (Emitter-Coupled Logic) register manufactured by onsemi. It integrates six differential D-type flip-flops with master reset functionality within a single circuit block. The device operates on a supply voltage range of 3 V to 5.5 V and features a propagation delay of 0.55 ns. It provides differential outputs capable of sourcing -50 mA and sinking 50 mA. Packaged in an LQFP-32 surface-mount format, it supports both inverting and non-inverting input polarities for flexible system integration.

Flip Flops Feature Summary

• Integrates six differential D-type flip-flops with master reset capability
• Supports high-speed operation with 0.55 ns propagation delay
• Provides fully differential inputs and outputs for noise immunity
• Operates across a wide 3 V to 5.5 V power supply range

Flip Flops Applications

• High-frequency data routing systems
• Clock distribution networks requiring low skew
• Telecommunications signal processing interfaces
• Test and measurement equipment digital logic stages

Flip Flops Procurement Notes

Verify the exact suffix against the manufacturer datasheet to confirm package type and temperature grade. Ensure compatibility with existing ECL biasing networks and termination resistors. Confirm availability status as specific suffixes may be subject to lifecycle changes or regional distribution restrictions.

Flip Flops Selection Notes

Select this component when designing circuits requiring multiple synchronized flip-flops with minimal propagation delay. The differential interface reduces common-mode noise, making it suitable for high-speed serial links. Verify that the PCB layout supports the LQFP-32 footprint and maintains impedance control for differential pairs.

Flip Flops Part Context

This part belongs to the MC10EP series of ECL registers, designed for demanding high-speed applications. It complements other onsemi ECL logic families by providing complex sequential functions. The series is engineered for telecommunications and industrial automation where reliable high-frequency timing is critical.

Flip Flops Replacement Considerations

Check for direct pin-compatible alternatives within the MC10EP family. Verify if upgraded suffixes offer improved thermal performance or extended temperature ranges. Cross-reference functional specifications to ensure equivalent drive strength and delay characteristics.
