MC100ELT28DTR2G

Translators, Level Shifters Overview

The MC100ELT28DTR2G is a mixed-signal translator integrating a differential PECL to TTL converter and a TTL to differential PECL converter within a single package. It operates on a +5 V supply with ground, eliminating the need for negative voltages. The device features flow-through pinouts and includes internal PECL input pulldown resistors. It provides PNP TTL inputs for minimal loading and 24 mA TTL outputs. The 100 Series incorporates temperature compensation. Typical propagation delays are 3.5 ns for PECL to TTL and 1.2 ns for TTL to PECL.

Translators, Level Shifters Feature Summary

• Integrates bidirectional translation between differential PECL and standard TTL logic levels in one component.
• Includes internal pull-down resistors on PECL inputs to manage open or floating states safely.
• Features fail-safe output defaults that drive high when inputs are left open or below specified thresholds.

Translators, Level Shifters Applications

• Backplane signal transmission and reception systems
• Interfacing high-speed PECL clock distribution networks with TTL-based logic circuits
• Converting TTL control signals to differential PECL formats for long-distance transmission

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DTR2G' corresponds to the TSSOP-8 tape and reel packaging configuration. Confirm the 'K' marking indicates the 100 Series variant with temperature compensation. Ensure the design accounts for the required 5V supply voltage range of 4.75 V to 5.25 V.

Translators, Level Shifters Selection Notes

Select this component when space constraints require combining both PECL-to-TTL and TTL-to-PECL translation functions into a single footprint. The TSSOP-8 package offers a compact solution compared to larger SOIC options. Consider the 100 Series temperature compensation if operating across wide thermal ranges.

Translators, Level Shifters Part Context

This part belongs to the MC100ELT28 family, which is designed for high-speed digital interfacing. It serves as a bridge between Positive ECL (PECL) standards and traditional Transistor-Transistor Logic (TTL). The device simplifies board layout by utilizing flow-through pinouts and requires only a positive power supply.

Translators, Level Shifters Replacement Considerations

MC10ELT28DTR2G is the non-temperature-compensated equivalent within the same package and pinout configuration.
