MC100EL58DG

Overview

The MC100EL58DG is a 2:1 multiplexer from the 100EL series, functionally equivalent to the E158 device but offering significantly faster propagation delays and output transition times. It features temperature compensation for stable performance across operating conditions. The device supports PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) and NECL mode with VEE ranging from -4.2 V to -5.7 V (VCC = 0 V). It includes internal input pulldown resistors on data and select lines, operates within a -40°C to +85°C temperature range, and meets RoHS standards.

Feature Summary

• Temperature compensated design ensures consistent AC performance across varying environmental conditions
• Internal input pulldown resistors integrated on data and select inputs to simplify circuit design
• 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 data acquisition systems
• Frequency division circuits
• Clock distribution networks
• Signal routing in high-frequency communication equipment

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the MC100EL58DG denotes the SOIC-8NB variant. Confirm compliance requirements such as RoHS status and lead-free specifications during procurement. Check current availability status as some devices in this family may be discontinued or recommended against new designs. Ensure proper handling procedures are followed due to the surface-mount nature of the component.

Selection Notes

Select the MC100EL58DG when temperature compensation is required for stable timing characteristics. Choose this part over the standard 10EL series if superior AC performance and thermal stability are critical. Consider the SOIC-8NB package constraints regarding board space and thermal dissipation. Verify that the system power supply aligns with either the PECL or NECL operating ranges specified in the datasheet.

Part Context

This component belongs to the MC10EL/100EL58 family of 5.0 V ECL multiplexers manufactured by onsemi. It serves as a high-performance alternative to legacy E158 devices, providing enhanced speed and reliability. The 100 series designation specifically indicates the inclusion of temperature compensation circuitry, distinguishing it from the standard 10 series variants which lack this feature.

Replacement Considerations

The MC10EL58DG is listed as a parameter-equivalent substitute. Both parts share functional equivalence but differ in temperature compensation capabilities. Verify pinout compatibility and electrical specifications before swapping. Note that the MC10EL58DG lacks the temperature compensation found in the MC100EL58DG.
