MC100LVEL58DT

Overview

The MC100LVEL58DT is a 3.3V ECL 2:1 multiplexer manufactured by onsemi, belonging to the 100 series which includes temperature compensation for stable performance across varying thermal conditions. It operates in PECL mode with VCC ranging from 3.0V to 3.8V and VEE at 0V, or in NECL mode with VCC at 0V and VEE between -3.0V and -3.8V. The device features a typical propagation delay of 500 ps and supports a maximum operating frequency exceeding 3 GHz. It utilizes an 8-TSSOP surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Temperature-compensated design ensures consistent electrical characteristics across the specified industrial temperature range.
• Integrated internal input pull-down resistors on data and select pins reduce external component requirements and improve signal stability.
• Default low output state when inputs are open or held at VEE prevents undefined logic states during initialization or fault conditions.

Applications

• High-speed data path switching in communication systems
• Random logic configuration in digital circuits
• Signal routing in high-frequency processing equipment

Procurement Notes

Verify the specific suffix 'DT' corresponds to the tape-and-reel packaging format, as this affects handling and storage requirements. Confirm RoHS compliance status for the specific manufacturing batch. Ensure the procurement source provides valid traceability documentation for the 100 series component. Check for any recent product change notices that may affect pinout or electrical specifications.

Selection Notes

Select this component when a 2:1 multiplexing function is required with strict timing constraints and ECL compatibility. The 100 series selection is appropriate for designs needing temperature compensation without external circuitry. Consider the 8-TSSOP package constraints regarding PCB space and thermal dissipation. Verify that the system power supply aligns with the 3.3V PECL or NECL operating ranges defined in the datasheet.

Part Context

This device is part of the MC100LVEL family of high-speed ECL logic components. It shares functional equivalence with older EL58 devices but offers improved speed and integrated temperature compensation characteristic of the 100 series. It serves as a direct replacement for legacy multiplexers in existing ECL-based architectures requiring modern reliability standards.

Replacement Considerations

The MC100LVEL58DG is a documented equivalent variant differing primarily in tube packaging instead of tape-and-reel. Both share identical electrical characteristics and pinouts. Verify package compatibility before substitution.
