MC100ELT25D

Translators, Level Shifters Overview

The MC100ELT25D is a differential ECL to TTL translator manufactured by onsemi. 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 24 mA TTL outputs. It includes internal input 50 kΩ pulldown resistors and an internally generated VBB reference voltage for single-ended inputs or AC coupling rebiasing. The component is housed in an 8-lead SOIC package.

Translators, Level Shifters Feature Summary

• Converts differential ECL signals to standard TTL logic levels
• Includes an internally generated VBB pin for single-ended operation and AC coupling biasing
• Features internal input pulldown resistors to manage open input states

Translators, Level Shifters Applications

• Clock signal translation between ECL sources and TTL receivers
• Data signal conversion in high-speed digital systems
• Interfacing ECLinPS components with TTL logic circuits

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-8 package variant. Confirm that the MC100 series designation ensures temperature compensation is included. Ensure the application environment supports the required dual power supply rails (+5V and -5V). Validate that the load conditions match the datasheet specifications for guaranteed AC parameters.

Translators, Level Shifters Selection Notes

Select this component when interfacing differential ECL drivers with TTL loads requiring high speed. The MC100 series provides temperature compensation compared to the MC10 series. Consider the 8-lead SOIC footprint for space-constrained designs. Verify that the system can accommodate the necessary negative supply voltage for proper ECL operation.

Translators, Level Shifters Part Context

This part belongs to the MC10ELT/100ELT family of translators designed for ECLinPS applications. The 100 series specifically incorporates temperature compensation to maintain performance stability across varying thermal conditions. It serves as a bridge between high-speed ECL clock/data lines and standard TTL interfaces.

Translators, Level Shifters Replacement Considerations

MC10ELT25D is functionally equivalent but lacks the temperature compensation found in the MC100 series.
