MC100EPT21DG

Translators, Level Shifters Overview

The MC100EPT21DG is a differential LVPECL/LVDS/CML to LVTTL/LVCMOS translator manufactured by onsemi. It operates within a supply voltage range of 3.0 V to 3.6 V with ground at 0 V. 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 applications. The component is housed in an 8-lead SOIC package.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL, LVDS, or CML input signals to LVTTL or LVCMOS outputs using only +3.3 V and ground supplies.
• Includes a dedicated VBB output pin that facilitates capacitive coupling in single-ended or differential input configurations.
• Incorporates temperature compensation characteristics inherent to the 100 Series logic family.

Translators, Level Shifters Applications

• Translation of clock signals between different voltage domains
• Translation of data signals between different voltage domains
• Interfacing high-speed differential sources with standard logic receivers

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'DG' corresponds to the SOIC-8 package configuration when sourcing components. Confirm RoHS compliance status and Pb-Free designation requirements against current manufacturing standards. Ensure the procurement specification matches the exact datasheet revision to guarantee accurate electrical parameter alignment.

Translators, Level Shifters Selection Notes

Select this component when interfacing differential ECL-family inputs with standard TTL or CMOS logic levels. The device requires only a single positive supply voltage, simplifying power distribution. Consider the VBB output feature if capacitive coupling is preferred over direct connection for the input stage.

Translators, Level Shifters Part Context

This part belongs to the MC100EPT21 series of translators designed for high-speed signal conversion. It is distinct from other variants such as the DR2G (reel packaging) or DTG (TSSOP package). The DG suffix specifically denotes the small outline 8-lead SOIC package format suitable for surface mount assembly.

Translators, Level Shifters FAQ

How should the VBB pin be utilized?

The VBB pin provides an output reference voltage that can be used for capacitive coupling in single-ended or differential input modes. For single-ended direct connections, an external voltage reference source should be used instead.

What are the input voltage compatibility options?

The device accepts differential LVPECL, LVDS, or positive CML input levels. It translates these directly to LVTTL or LVCMOS output levels.
