MC10E156FN

Overview

The MC10E156FN is a high-speed ECL 3-bit 4:1 multiplexer-latch integrated circuit manufactured by onsemi. It operates within the 10E series and features a 28-lead PLCC package with dimensions of 11.51x11.51 mm. The device supports PECL mode with VCC ranging from 4.2V to 5.7V (VEE=0V) and NECL mode with VCC=0V and VEE from -4.2V to -5.7V. It includes differential outputs and a master reset function that overrides other controls to set Q outputs low.

Feature Summary

• Integrates 3-bit 4:1 multiplexing with latch functionality in a single component
• Supports both PECL and NECL logic families for flexible power supply configurations
• Features differential outputs to enhance signal integrity in high-speed applications
• Includes a master reset input that forces Q outputs to a low state

Applications

• High-speed data routing systems requiring multiplexing and temporary storage
• Clock distribution networks utilizing ECL logic standards
• Telecommunications equipment processing differential signals
• Test and measurement instruments needing fast switching capabilities

Procurement Notes

Verify the specific suffix 'FN' against current datasheets to confirm package type and lead-free status, as manufacturing updates may alter these attributes. Confirm availability status, as this part number may be discontinued or subject to limited stock constraints. Ensure compatibility with existing PCB footprints for the 28-lead PLCC format before finalizing procurement decisions.

Selection Notes

Select this component when a combined multiplexer and latch function is required within an ECL-based design. It is suitable for applications demanding low propagation delay and high-frequency operation up to typical ECL limits. Consider the 28-lead PLCC package constraints and ensure the system power supply aligns with the specified PECL or NECL voltage ranges for proper operation.

Part Context

This device belongs to the onsemi 10E series of emitter-coupled logic components. These parts are designed for high-speed digital applications where speed is critical. The 10E series typically offers performance characteristics superior to standard TTL or CMOS logic at high frequencies, making it a staple in specialized high-speed computing and communication architectures.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 10E family, such as variants with different suffixes indicating updated packaging or environmental compliance. Verify if newer generation ECL devices offer improved speed or lower power consumption while maintaining functional equivalence.
