MC100EPT21DR2G

Translators, Level Shifters Overview

The MC100EPT21DR2G is a differential LVPECL/LVDS/CML to LVTTL/LVCMOS translator manufactured by onsemi. It operates with a supply voltage range of 3.0 V to 3.6 V and ground, requiring only positive power rails. The device features a typical propagation delay of 1.4 ns and supports maximum frequencies exceeding 275 MHz. It provides 24 mA TTL output drive capability and includes a VBB output reference voltage for capacitive coupling in single-ended or differential input modes. Packaged in an SOIC-8 format, it is designed for clock and data signal translation applications.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL, LVDS, or CML signals to LVTTL or LVCMOS logic levels
• Includes a dedicated VBB output pin to facilitate capacitive coupling for input termination
• Supports both single-ended and differential input configurations via the VBB reference

Translators, Level Shifters Applications

• Clock signal translation between high-speed differential sources and TTL receivers
• Data signal interfacing between LVDS/CML transmitters and LVTTL/LVCMOS logic circuits
• High-frequency communication systems requiring level shifting from PECL standards

Translators, Level Shifters Procurement Notes

Verify that the specific order suffix DR2G corresponds to the SOIC-8 package type and tape-and-reel shipping configuration as defined in the official ordering information. Confirm compliance requirements such as RoHS status and lead-free specifications match project constraints before finalizing procurement documentation.

Translators, Level Shifters Selection Notes

Select this component when translating differential ECL-family signals to standard TTL/CMOS levels using a single 3.3 V supply. Ensure the application requires the specific VBB reference functionality for capacitive coupling. Verify that the operating temperature range of -40°C to +85°C meets environmental requirements and that the SOIC-8 package dimensions fit the PCB layout.

Translators, Level Shifters Part Context

This part belongs to the MC100EPT21 series within onsemi's ECL logic family. It is specifically engineered to bridge the gap between low-voltage differential signaling standards and traditional transistor-transistor logic interfaces. The series utilizes temperature compensation techniques inherent to the 100 Series architecture to maintain performance stability across varying thermal conditions.

Translators, Level Shifters Replacement Considerations

Check the datasheet ordering information for alternative packages of the same function, such as TSSOP-8 (MC100EPT21DTR2G) or DFN8 (MC100EPT21MNR4G). These variants share identical electrical characteristics but differ in physical footprint and mounting style.
