MC10EL58DG

Overview

The MC10EL58DG is a 2:1 multiplexer from the onsemi 10EL series, designed for high-speed ECL applications. It operates in PECL mode with VCC between 4.2 V and 5.7 V (VEE = 0 V) or NECL mode with VEE between −4.2 V and −5.7 V (VCC = 0 V). The device features a propagation delay of 230 ps typical and supports a maximum toggle frequency of 1.5 GHz. Power supply current is typically 17 mA. It includes internal input pulldown resistors on data and select lines.

Feature Summary

• High-speed AC performance with significantly faster propagation delays than standard ECL devices
• Dual-mode operation supporting both PECL and NECL voltage ranges
• Internal input pulldown resistors on data and select inputs to prevent floating states

Applications

• High-performance digital signal routing requiring low latency
• Clock distribution networks utilizing ECL logic families
• Data selection circuits in telecommunications infrastructure

Procurement Notes

Verify the specific ordering suffix to confirm package type, as the DG suffix denotes SOIC-8. Note that this specific part number is listed as discontinued in official documentation; alternative active versions such as DR2G or DTG may be required for new designs. Confirm RoHS compliance and Pb-free status through current manufacturer channels before procurement.

Selection Notes

Select the MC10EL58DG when ultimate AC performance is required over standard ECL alternatives like the E158. Ensure the design environment supports ECL power supplies, either PECL or NECL configurations. Verify thermal management requirements given the junction-to-ambient resistance values for the SOIC-8 package under varying airflow conditions.

Part Context

This component belongs to the MC10EL/100EL family of ECL logic devices. The 10EL series offers enhanced speed compared to legacy E158 parts. The MC100EL variant includes temperature compensation, whereas the MC10EL series does not. Both share similar pinouts and functional logic but differ in electrical characteristics across temperature ranges.

Replacement Considerations

The MC100EL58 is functionally equivalent but includes temperature compensation. Active replacements include MC10EL58DR2G (SOIC-8 Tape & Reel) and MC10EL58DTG (TSSOP-8). Consult onsemi for current availability as the DG variant is discontinued.
