MC100ELT28DR2G

Translators, Level Shifters Overview

The MC100ELT28DR2G is a dual bidirectional voltage level translator manufactured by onsemi, designed to interface between TTL and differential PECL logic families. It integrates two independent translation channels within a single package, supporting both PECL-to-TTL and TTL-to-PECL signal conversion. The device operates at a supply voltage of 5 V with an operating range from 4.75 V to 5.25 V. It features typical propagation delays of 3.5 ns for PECL to TTL conversion and 1.2 ns for TTL to PECL conversion. The component utilizes PNP inputs for minimal loading and provides 24 mA TTL output drive capability.

Translators, Level Shifters Feature Summary

• Bidirectional translation between TTL and differential PECL logic levels in a single package
• Internal pull-down resistors on PECL inputs to ensure defined states during open conditions
• Outputs default high when inputs are left open or below specified thresholds
• Temperature compensated design characteristic of the 100 Series

Translators, Level Shifters Applications

• Backplane signal transmission and reception across mixed logic domains
• Interfacing TTL-based controllers with PECL-based peripheral devices
• High-speed data communication systems requiring voltage level shifting

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DR2G' corresponds to the SOIC-8 tape and reel packaging configuration. Confirm that the active status aligns with current manufacturing schedules, as electronic components may undergo lifecycle changes. Ensure compatibility with RoHS compliance requirements for your assembly process.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between standard TTL and differential PECL is required without separate unidirectional chips. Consider the 100 Series temperature compensation for wider thermal stability compared to the 10 Series. Verify that the 5 V supply voltage matches the system power architecture and that the SOIC-8 footprint fits the PCB layout constraints.

Translators, Level Shifters Part Context

This part belongs to the MC100ELT series of ECLinPS translators. It shares functional similarities with the MC10ELT28 but includes internal temperature compensation. The DR2G suffix indicates surface mount packaging in a tape and reel format suitable for automated assembly processes.

Translators, Level Shifters Replacement Considerations

MC10ELT28DR2G serves as a direct functional substitute, differing primarily in the absence of temperature compensation.
