MC100ELT21DR2G

Translators, Level Shifters Overview

The MC100ELT21DR2G is a single-channel differential PECL to TTL translator manufactured by onsemi. It operates within a VCC range of 4.75 V to 5.25 V with GND at 0 V. The device features a typical propagation delay of 3.5 ns, with maximum delays of 5.5 ns across the operating temperature range of -40°C to +85°C. It provides a 24 mA TTL output drive capability and supports a maximum toggle frequency of 100 MHz. The component is housed in an SOIC-8 package.

Translators, Level Shifters Feature Summary

• Translates differential PECL signals to standard TTL logic levels using only positive supply voltage.
• Includes an internally generated VBB reference pin for biasing unused differential inputs or AC-coupled signals.
• Features flow-through pinouts to simplify PCB layout and routing.
• Incorporates internal input pulldown resistors and ensures Q output defaults LOW if inputs are open.

Translators, Level Shifters Applications

• Interfacing high-speed PECL clock sources with TTL-based digital logic circuits
• Level translation in space-constrained communication systems requiring low power consumption
• Signal conditioning for differential data lines converting to single-ended TTL outputs

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix DR2G corresponds to the SOIC-8 tape and reel packaging configuration. Confirm RoHS compliance and lead-free status as specified in the manufacturer's documentation. Ensure the design accounts for the specific thermal resistance values associated with the SOIC-8 package under expected airflow conditions.

Translators, Level Shifters Selection Notes

Select this component when interfacing 5V PECL sources directly to TTL loads without requiring negative supply rails. The MC100 series variant offers temperature compensation compared to the MC10 series. Consider the 3.5 ns typical delay and 100 MHz maximum toggle frequency for high-speed signal integrity requirements.

Translators, Level Shifters Part Context

This device belongs to the MC10ELT/100ELT family of ECLinPS translators. It is designed for applications prioritizing performance and low power in small outline packages. The 100 Series specifically includes temperature compensation features to maintain stable operation across the industrial temperature range.

Translators, Level Shifters Replacement Considerations

MC10ELT21DG serves as a tube-packaged alternative within the same functional family. MC100ELT21DTG provides the same functionality in a TSSOP-8 package. Verify pinout compatibility and package dimensions before substituting.
