Translators, Level Shifters Overview

The MC100EPT21DR2 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. 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.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL, LVDS, or CML signals to LVTTL or LVCMOS logic levels using only positive supply and ground connections.
• Includes a dedicated VBB output pin that facilitates capacitive coupling for both single-ended and differential input configurations.
• Incorporates temperature compensation within the 100 Series architecture to maintain performance across the operating temperature range.

Translators, Level Shifters Applications

• Clock signal translation between high-speed differential sources and TTL-compatible receivers
• Data signal level shifting from LVPECL or LVDS interfaces to LVTTL/LVCMOS domains
• Interfacing differential clock distribution networks with standard logic circuits

Translators, Level Shifters Procurement Notes

Verify the specific package suffix 'DR2' corresponds to the SOIC-8 tape and reel configuration as listed in the ordering information. Confirm RoHS compliance and Pb-free status through official manufacturer documentation. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range and 3.0 V to 3.6 V supply voltage limits.

Translators, Level Shifters Selection Notes

Select this component when interfacing differential ECL-family inputs with standard TTL outputs requiring high-speed translation. The device is suitable for applications needing a single +3.3 V supply rail. Consider the SOIC-8 package availability and thermal characteristics if board space is constrained. Verify input signal swing requirements against the specified common mode range.

Translators, Level Shifters Part Context

This part belongs to the MC100EPT21 family of translators designed for high-speed digital interfaces. The DR2 suffix indicates a specific reel packaging format for the SOIC-8 variant. The family utilizes temperature-compensated circuitry to ensure stable operation across industrial temperature ranges while maintaining low propagation delays.

Translators, Level Shifters Replacement Considerations

MC100EPT21DG (SOIC-8 Rail), MC100EPT21DTG (TSSOP-8 Rail), MC100EPT21DTR2G (TSSOP-8 Reel), MC100EPT21MNR4G (DFN8 Reel). All variants share identical electrical specifications; selection depends on required package type and shipping quantity.

Translators, Level Shifters FAQ

How should the VBB pin be configured for single-ended capacitive coupling?

For single-ended capacitive coupling, the VBB output should be tied to the D input. Driving the D input creates either a non-inverting buffer or an inverting buffer depending on the connection logic.

What is the function of the internal pull-up and pull-down resistors on the D input?

The device includes internal 50 kΩ pull-up and pull-down resistors on the D and D* pins. These default the input to half of VCC when left open, providing a defined state without external components.
