MC100EP58DR2G

Overview

The MC100EP58DR2G is a high-speed 3.3 V/5 V ECL 2:1 multiplexer manufactured by onsemi. It operates within a supply voltage range of 3.0 V to 5.5 V in PECL mode and -3.0 V to -5.5 V in NECL mode. The device features a typical propagation delay of 310 ps and supports frequencies exceeding 3 GHz. It includes temperature compensation for stable performance across varying thermal conditions. The component is housed in an SOIC-8 surface-mount package and functions with differential ECL inputs and outputs.

Feature Summary

• Temperature-compensated design ensures consistent signal integrity across operating temperatures
• Supports both PECL and NECL power architectures for flexible system integration
• High-frequency operation capability suitable for demanding data transmission applications

Applications

• High-speed data communication systems requiring low latency
• Frequency-selective routing in RF and microwave circuits
• Signal distribution networks in telecommunications infrastructure

Procurement Notes

Verify the specific suffix DR2G against official datasheets to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact logic family requirements. Cross-reference manufacturer documentation for any recent pinout revisions or environmental declarations prior to final procurement decisions.

Selection Notes

Select this component when designing systems requiring precise signal selection at gigahertz speeds. The integrated temperature compensation reduces the need for external calibration circuitry. Verify that the target PCB layout accommodates the SOIC-8 footprint and that the power supply rails align with the specified PECL or NECL voltage ranges for optimal noise immunity.

Part Context

This device belongs to the MC100EP series, which utilizes emitter-coupled logic technology optimized for high-speed digital applications. The series is characterized by its ability to operate reliably in harsh electrical environments while maintaining strict timing specifications. It serves as a critical interconnect element in complex digital architectures requiring rapid data path switching.

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 differ in specific electrical characteristics such as propagation delay or input impedance. Evaluate these parameters against current design constraints before substitution.
