MC100EP58D

Overview

The MC100EP58D is a 2:1 multiplexer from the onsemi 100 series, designed for high-speed ECL applications. It operates with a typical propagation delay of 310 ps and supports maximum frequencies exceeding 3 GHz. The device accommodates dual power supply configurations: PECL mode utilizes VCC between 3.0 V and 5.5 V with VEE at 0 V, while NECL mode uses VCC at 0 V and VEE between -3.0 V and -5.5 V. It features temperature compensation for stable performance across varying thermal conditions and includes input default states to ensure reliable output levels during open-circuit conditions.

Feature Summary

• Temperature-compensated design ensures consistent electrical performance across different operating temperatures.
• High-speed signal processing capability suitable for demanding data transmission requirements.
• Flexible power architecture supporting both positive and negative emitter-coupled logic voltage ranges.
• Integrated input protection defaults outputs to low state when inputs are left open or pulled to VEE.

Applications

• High-speed data communication systems requiring precise signal routing
• Frequency-sensitive electronic circuits needing stable multiplexing
• Complex digital architectures utilizing differential ECL signaling standards

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-8 surface-mount package configuration before procurement. Confirm that the selected variant meets the required RoHS compliance standards for lead-free and halogen-free manufacturing. Ensure the ordering documentation explicitly references the MC100EP58D part number to distinguish it from other series members like the MC10EL58. Cross-reference the datasheet revision history to validate current production status and any potential pinout changes.

Selection Notes

Select this component when system designs demand low propagation delay and wide voltage tolerance within ECL families. The 100 series designation indicates integrated temperature compensation, making it preferable over standard variants for environments with significant thermal fluctuations. Verify that the application circuitry can support the specified dual-supply requirements for either PECL or NECL operation modes effectively.

Part Context

This device belongs to the broader 100EP logic family, which emphasizes enhanced speed and thermal stability compared to earlier generations. It serves as a functional equivalent to legacy EL58 components but offers improved timing characteristics. The multiplexer topology allows for efficient selection between two distinct data inputs based on a single control signal, facilitating complex data path management in high-frequency digital environments.

Replacement Considerations

Direct substitutes include the MC10EP58DTG, though availability may vary due to obsolescence status. Alternative sources might offer the MC100EP58DTG through specialized distributors. Verify pin compatibility and electrical specifications against the original datasheet before implementing any cross-brand replacements.
