MC100EP58DG

Overview

The MC100EP58DG is a single 2:1 multiplexer from the onsemi MC100 series, designed for high-speed differential ECL applications. 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 maximum frequencies exceeding 3 GHz. It includes temperature compensation for stable performance across varying thermal conditions. Packaged in an 8-pin SOIC surface-mount format, it functions as a direct replacement for EL58 and LVEL58 devices.

Feature Summary

• Temperature-compensated design ensures consistent signal integrity across wide operating temperature ranges.
• Supports flexible power configurations through compatibility with both PECL and NECL logic families.
• Internal input pull-down resistors maintain defined low states when inputs are open or floating.

Applications

• High-speed data communication systems requiring precise signal routing
• Frequency-sensitive electronic circuits demanding minimal transmission latency
• Complex digital architectures utilizing differential ECL signaling standards

Procurement Notes

Verify that the specific suffix 'DG' corresponds to the SOIC-8 package variant rather than TSSOP alternatives within the same family. Confirm RoHS compliance status directly with the manufacturer documentation prior to integration. Ensure procurement channels provide original manufacturer traceability to avoid counterfeit components in high-reliability designs.

Selection Notes

Select this component when system requirements demand sub-nanosecond switching speeds combined with robust thermal stability. It is suitable for designs needing internal pull-down functionality to simplify external circuitry. Consider alternative variants if lower power consumption is prioritized over the highest possible frequency performance.

Part Context

This part belongs to the MC100EP series, which represents advancedEmitter-Coupled Logic technology optimized for speed. The 100 series designation specifically indicates the inclusion of temperature compensation circuits not found in standard versions. This places the device in a category of premium high-frequency logic gates intended for professional telecommunications and computing infrastructure.

Replacement Considerations

MC10EL58DG serves as a functional equivalent with comparable pinout and logical operations. Designers should verify that the specific package dimensions match the existing PCB footprint before substitution.
