MC100ELT28DTR2

Translators, Level Shifters Overview

The MC100ELT28DTR2G is a dual translator integrating TTL to differential PECL and differential PECL to TTL conversion within an 8-lead TSSOP package. It operates on a single +5 V supply with GND=0 V. The device features flow-through pinouts for simplified backplane signal routing. The 100 Series includes temperature compensation. Typical propagation delays are 3.5 ns for PECL to TTL and 1.2 ns for TTL to PECL. Operating voltage range is 4.75 V to 5.25 V.

Translators, Level Shifters Feature Summary

• Integrates bidirectional translation between TTL and differential PECL logic levels in a single package
• Features flow-through pinout configuration to facilitate direct backplane signal routing
• Includes internal PECL input pulldown resistors and open-input default high states for reliability
• Provides PNP TTL inputs for minimal loading and 24 mA TTL output drive capability

Translators, Level Shifters Applications

• Backplane signal transmission and reception across mixed logic domains
• Interfacing TTL-based systems with differential PECL clock or data lines
• High-speed digital communication circuits requiring level translation

Translators, Level Shifters Procurement Notes

Verify the complete part number suffix, as 'DTR2' indicates specific packaging and compliance attributes. Confirm RoHS and halogen-free status requirements against project specifications. Ensure the ordering code matches the exact manufacturer designation to avoid compatibility issues with design files.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between TTL and differential PECL is required without separate devices. The 100 Series offers temperature compensation for enhanced stability compared to the standard 10 Series. Verify that the system operates within the specified 4.75 V to 5.25 V supply range and utilizes the appropriate TSSOP-8 footprint.

Translators, Level Shifters Part Context

This device belongs to the MC10EL/100ELT28 family of translators manufactured by onsemi. The 100 Series variant provides temperature-compensated performance characteristics suitable for wider operating conditions. It serves as a bridge between standard TTL logic families and Positive ECL (PECL) standards commonly used in high-speed networking and telecommunications equipment.

Translators, Level Shifters Replacement Considerations

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