MC100EP58DTG

Overview

The MC100EP58DTG is a 3.3 V/5 V ECL 2:1 multiplexer from onsemi, part of the temperature-compensated MC100 series. It operates with a supply voltage range of 3.0 V to 5.5 V in PECL mode (VCC) or -3.0 V to -5.5 V in NECL mode (VEE). The device features a typical propagation delay of 310 ps and supports frequencies exceeding 3 GHz. It provides differential ECL outputs and includes internal pull-down resistors for input stability.

Feature Summary

• Temperature-compensated design ensures stable performance across varying environmental conditions.
• Supports both PECL and NECL power modes for flexible system integration.
• Internal input pull-down resistors prevent undefined states when inputs are open.
• High-speed operation suitable for demanding data transmission applications.

Applications

• High-speed data communication systems
• Signal routing and selection circuits
• Frequency-sensitive electronic designs

Procurement Notes

Verify the specific suffix DTG corresponds to the TSSOP-8 package and tube packaging configuration. Confirm RoHS compliance and lead times directly with authorized distributors, as availability varies. Ensure the selected variant matches the required operating voltage range and logic family specifications for your circuit design.

Selection Notes

Select this component when a high-speed, temperature-stable multiplexer is required for ECL-based architectures. It is suitable for designs needing reliable signal selection with minimal propagation delay. Consider the available supply voltage options and the benefit of internal pull-downs for simplified input circuitry compared to non-compensated alternatives.

Part Context

This device belongs to the MC100EP series, which offers enhanced AC performance over older ECL families. The 100 series specifically incorporates temperature compensation, distinguishing it from standard variants. It serves as a modern replacement for legacy components like the EL58, providing improved speed and reliability for contemporary high-frequency applications.

Replacement Considerations

The MC100EP58DTG is functionally equivalent to the MC10EL58 and MC100EL58. Designers may also consider the MC100EP58 without the DTG suffix if package compatibility allows. Verify pinout consistency when substituting with other ECL multiplexers in existing layouts.
