MC100EL58DTG

Overview

The MC100EL58DTG is a 2:1 multiplexer from the 100EL series, functionally equivalent to the E158 device but with significantly faster propagation delays and output transition times. It features temperature compensation for stable performance across varying conditions. The device operates in PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) or NECL mode with VCC at 0 V and VEE from −4.2 V to −5.7 V. It includes internal input pulldown resistors on data and select lines, ensuring defined states when inputs are open.

Feature Summary

• Temperature compensated design ensures consistent AC performance across operating temperatures
• Internal input pulldown resistors on data and select pins eliminate need for external pull-down components
• Supports both PECL and NECL logic families with wide supply voltage flexibility
• High-speed operation suitable for applications requiring ultimate AC performance

Applications

• High-speed signal routing in communication systems
• Data acquisition systems requiring fast switching
• Clock distribution networks
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix DTG corresponds to the TSSOP-8 package configuration required for your PCB layout. Confirm RoHS compliance status as per current manufacturer declarations. Ensure thermal management considerations align with the junction-to-ambient resistance values specified for the TSSOP-8 package under your expected airflow conditions.

Selection Notes

Select this component when temperature stability is critical for maintaining signal integrity in high-speed ECL circuits. The 100 series offers superior thermal performance compared to the standard 10 series. Consider the TSSOP-8 package if space constraints favor surface-mount technology over SOIC. Verify that the internal pulldown resistor values meet your input impedance requirements without additional external circuitry.

Part Context

This device belongs to onsemi's MC10EL/100EL family of ECL multiplexers. The 100 series designation indicates enhanced temperature compensation features not present in the base 10 series models. It serves as a direct functional replacement for legacy E158 devices while offering improved speed characteristics. The DTG suffix specifically denotes the TSSOP-8 package variant.

Replacement Considerations

MC10EL58DTG is the non-temperature-compensated counterpart within the same package. For discontinued SOIC variants, MC100EL58DG provides equivalent functionality in a different footprint.
