MC10ELT25DTR2

Translators, Level Shifters Overview

The MC10ELT25DTR2 is a single differential ECL to TTL translator manufactured by onsemi in a TSSOP-8 package. It operates with VCC = 4.5 V to 5.5 V and VEE = −4.2 V to −5.7 V. The device features a typical propagation delay of 2.6 ns, a maximum toggle frequency (FMAX) of 100 MHz, and provides 24 mA TTL output drive capability. Internal input pulldown resistors ensure the Q output defaults HIGH when inputs are open or below 1.3 V.

Translators, Level Shifters Feature Summary

• Converts differential ECL signals to standard TTL logic levels
• Includes an internal reference voltage output (VBB) for AC coupling or single-ended input biasing
• Features flow-through pinouts for simplified circuit layout
• Provides high-speed performance suitable for space-constrained applications

Translators, Level Shifters Applications

• High-speed data acquisition systems requiring ECL-to-TTL interfacing
• Telecommunications equipment utilizing differential signaling
• Test and measurement instruments needing fast signal translation
• Computer peripheral interfaces bridging ECL and TTL domains

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'DTR2' corresponds to the TSSOP-8 tape and reel configuration containing 2500 units per reel. Confirm that the required power supplies (+5 V and -5.2 V/-4.5 V) match the recommended operating conditions specified in the datasheet. Ensure compatibility with the moisture sensitivity level and flammability ratings for your assembly process.

Translators, Level Shifters Selection Notes

Select this component when a single gate is sufficient for translating differential ECL inputs to TTL outputs. Consider the TSSOP-8 package if board space is limited compared to the SOIC-8 option. Verify that the system can support the dual power supply requirement (positive and negative rails) inherent to ECL logic families before finalizing the design.

Translators, Level Shifters Part Context

This part belongs to the MC10ELT/100ELT series of translators designed for high-performance digital applications. The 100 Series variant includes temperature compensation, while the standard 10 Series offers baseline performance. Both series share identical pinouts and electrical characteristics, differing primarily in internal temperature stability mechanisms.

Translators, Level Shifters Replacement Considerations

MC10ELT25DR2 serves as a direct functional substitute using the SOIC-8 package instead of TSSOP-8. MC100ELT25DTR2 is available for designs requiring temperature-compensated operation within the same TSSOP-8 footprint and reel packaging.
