MC100EL58DTR2G

Overview

The MC100EL58DTR2G is a 5.0V ECL 2:1 multiplexer from the 100 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 thermal 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 VEE ranging from -4.2 V to -5.7 V (VCC = 0 V). It includes internal input pulldown resistors on data and select lines, ensuring defined logic 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 power supply configurations for flexible system integration

Applications

• High-speed signal routing in communication systems
• Data acquisition systems requiring low latency switching
• Clock distribution networks demanding minimal jitter

Procurement Notes

Verify the specific ordering suffix DTG or DR2G matches the required package type, as the datasheet lists multiple variants. Confirm current availability status directly with the manufacturer, as some related devices in this series have been discontinued. Ensure the selected part meets RoHS compliance requirements for your assembly process.

Selection Notes

Select the MC100EL58DTR2G when temperature stability is critical for maintaining signal integrity in high-frequency applications. Choose this over the standard 10EL series if operation across extreme environmental variations is required. Verify that the system power supply aligns with either the PECL or NECL voltage ranges specified in the datasheet.

Part Context

This component belongs to the MC10EL/100EL family of high-performance ECL logic devices manufactured by onsemi. The 100 Series designation specifically indicates the inclusion of temperature compensation circuitry, distinguishing it from the standard 10EL series which lacks this feature. It serves as a direct functional replacement for legacy E158 multiplexers with improved speed characteristics.

Replacement Considerations

MC10EL58DG is listed as a parameter-equivalent alternative within the same product family.
