MC100ELT25DTG

Translators, Level Shifters Overview

The MC100ELT25DTG is a single-gate differential ECL to TTL translator in an 8-lead TSSOP package. It requires +4.5 V to +5.5 V (VCC) and -4.2 V to -5.7 V (VEE). The device features a typical propagation delay of 2.6 ns, maximum toggle frequency of 100 MHz, and 24 mA TTL output drive capability. Internal input pulldown resistors are 75 kΩ. Operating temperature range is -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Converts differential ECL signals to standard TTL logic levels
• Includes internally generated VBB reference voltage for single-ended input configuration
• Contains internal 75 kΩ input pulldown resistors to simplify circuit design
• Features Q output defaulting HIGH when inputs are open or below 1.3 V

Translators, Level Shifters Applications

• Clock signal translation between ECL sources and TTL receivers
• Data signal interfacing where space and low power consumption are critical
• High-speed digital systems requiring flow-through pinout compatibility

Translators, Level Shifters Procurement Notes

Verify the DT suffix corresponds to the TSSOP-8 package type. Confirm the '00' series designation indicates the inclusion of temperature compensation features. Ensure supply voltages match the specified ranges: VCC between 4.5 V and 5.5 V, and VEE between -4.2 V and -5.7 V relative to ground.

Translators, Level Shifters Selection Notes

Select this component when interfacing high-speed ECL clock or data lines with TTL-compatible loads. The TSSOP-8 package offers a compact footprint suitable for space-constrained designs. The 100 Series variant provides temperature compensation, enhancing performance stability across the industrial temperature range compared to non-compensated alternatives.

Translators, Level Shifters Part Context

This part belongs to the MC10ELT/100ELT family of differential ECL to TTL translators. The MC100ELT25DTG specifically utilizes the TSSOP-8 surface-mount package. It shares functional similarities with other members like the MC10ELT25 but differs in packaging and specific electrical characteristics such as temperature compensation found in the 100 Series.

Translators, Level Shifters Replacement Considerations

MC10ELT25DTG serves as a direct alternative within the same family, differing primarily by the absence of temperature compensation features.

Translators, Level Shifters FAQ

How should the VBB pin be handled if single-ended input is not used?

If the VBB pin is not utilized for single-ended input referencing or AC coupling rebiasing, it should be left open.

What is the function of the internal input pulldown resistors?

The internal 75 kΩ pulldown resistors eliminate the need for external components to define input states, simplifying the circuit layout and reducing board space requirements.
