MC100EP58DTR2G

Overview

The MC100EP58DTR2G is a 2:1 multiplexer from the onsemi 100 series, designed for high-speed differential 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, functioning in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE at 0 V) or NECL mode with VEE ranging from -3.0 V to -5.5 V (VCC at 0 V). It is housed in an 8-TSSOP surface-mount package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Features low propagation delay and high-frequency operation suitable for rapid signal processing.
• Supports flexible power architectures through compatible PECL and NECL voltage ranges.
• Includes internal input pull-down resistors to maintain stable default output states during open inputs.

Applications

• High-speed data communication systems requiring precise signal synchronization
• Multiplexing circuits in frequency-sensitive electronic designs
• Signal routing in complex digital logic environments

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number and ordering suffix with official datasheets. Confirm that the specific package variant matches design requirements. Ensure compliance with environmental standards such as RoHS and lead-free specifications before integration into production workflows.

Selection Notes

Select this component when system architecture demands minimal signal latency and robust performance across varying thermal conditions. The integrated pull-down features simplify circuit design by reducing external component count. Verify that the available voltage rails align with the specified PECL or NECL operational modes for optimal functionality.

Part Context

This device belongs to the MC100EP series, which provides temperature-compensated performance for consistent operation across different environmental conditions. It serves as a functional equivalent to legacy EL58 devices while offering enhanced speed and reliability characteristics required in modern high-speed digital interfaces.

Replacement Considerations

The MC10EL58 and MC100EL58 are functionally equivalent alternatives within the same product family. These substitutes offer similar 2:1 multiplexing capabilities but may exhibit variations in propagation delay metrics. Evaluate timing constraints carefully before substituting to ensure compatibility with existing system specifications.

FAQ

How does the device handle open input conditions?

The Q output defaults to a low state when inputs are left open or pulled down to VEE, ensuring predictable behavior without external components.

What determines the selected data output?

The SEL input pin controls the selection between Data A and Data B inputs, directing the chosen signal to the differential outputs.
