MC100ELT25DTR2

Translators, Level Shifters Overview

The MC100ELT25DTR2 is a single-gate differential ECL to TTL translator manufactured by onsemi. It operates with VCC = 4.5 V to 5.5 V, VEE = −4.2 V to −5.7 V, and GND = 0 V. The device features a typical propagation delay of 2.6 ns and a maximum toggle frequency (fMAX) of 100 MHz. It provides 24 mA TTL outputs and includes internal input 50 kΩ pulldown resistors. The Q output defaults HIGH when inputs are open or below 1.3 V. It is housed in an 8-lead TSSOP package.

Translators, Level Shifters Feature Summary

• Converts differential ECL signals to standard TTL logic levels
• Includes temperature compensation for stable operation across the industrial range
• Features internally generated reference voltage (VBB) for AC coupling or single-ended biasing
• Provides high drive capability with 24 mA TTL outputs

Translators, Level Shifters Applications

• Interfacing ECL clock distribution networks with TTL-based digital systems
• High-speed data translation in telecommunications equipment
• Test and measurement instrumentation requiring fast signal conversion
• Industrial control systems utilizing mixed ECL/TTL architectures

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix 'R2' corresponds to the tape and reel packaging format specified in the datasheet. Confirm the specific variant matches the required package type and electrical characteristics. Ensure compatibility with the intended supply voltages and load conditions before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing ECL sources with TTL loads requiring high speed and low power consumption. The 100 Series offers temperature compensation compared to the standard 10 Series. Consider the TSSOP-8 package for space-constrained designs. Verify that the system can support the required dual positive and negative power supplies.

Translators, Level Shifters Part Context

This part belongs to the MC10ELT/100ELT family of differential ECL to TTL translators. The 100 Series variant includes temperature compensation, distinguishing it from the non-compensated 10 Series. These devices are designed for applications where space, performance, and low power are critical constraints.

Translators, Level Shifters Replacement Considerations

MC10ELT25DTR2 serves as a direct replacement for MC100ELT25DTR2 if temperature compensation is not required. MC100ELT25DT is the rail-pack equivalent. Verify pinout compatibility and electrical specifications before substituting.
