MC100EP58DT

Overview

The MC100EP58DT is a 2:1 multiplexer from the onsemi 100EP series, designed for high-speed ECL applications. It operates with a typical propagation delay of 310 ps and supports frequencies exceeding 3 GHz. The device accommodates PECL (VCC 3.0–5.5 V) and NECL (VEE -3.0 to -5.5 V) power configurations. It features temperature compensation for stable performance across varying thermal conditions and includes internal pull-down resistors that default outputs to low when inputs are open.

Feature Summary

• High-speed signal processing with minimal propagation delay for synchronous data integrity
• Temperature-compensated design ensures consistent AC performance across operating ranges
• Flexible power supply compatibility supporting both PECL and NECL logic families
• Fail-safe input configuration defaults output to low state during open-circuit conditions

Applications

• High-frequency communication systems requiring precise signal routing
• Fast data acquisition networks needing low-latency switching
• Telecommunications infrastructure utilizing ECL-based logic architectures

Procurement Notes

Verify the specific suffix 'DT' against the official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status and environmental declarations directly with the manufacturer or authorized distributors. Ensure voltage levels match the selected PECL or NECL mode requirements before integration.

Selection Notes

Select this component for designs demanding sub-nanosecond switching speeds within ECL ecosystems. Consider the 100EP series temperature compensation if the application involves significant thermal fluctuations. Verify that the system power rails align with the specified 3.0 V to 5.5 V range for optimal noise margins and signal integrity.

Part Context

This part belongs to the MC100EP family of emitter-coupled logic devices. It serves as a direct functional equivalent to legacy EL58 and LVEL58 components but offers improved speed characteristics. The 100EP series is engineered for robust performance in demanding digital environments where timing precision is critical.

Replacement Considerations

Direct substitutes include MC100EP58DG and MC100EP58DTR2G. Verify pinout compatibility and electrical parameters before substitution. Legacy equivalents such as EL58 may require level-shifting adjustments.
