MC10ELT28DG

Translators, Level Shifters Overview

The MC10ELT28DG is a dual unidirectional voltage level translator from the MC10EL series by onsemi. It facilitates signal conversion between ECL-family standards (PECL, CML, LVDS) and TTL/CMOS logic levels. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports bidirectional translation between PECL and TTL. Key electrical parameters include a maximum propagation delay of 1.35 ns for DTTL to QECL transitions and 5.5 ns for DECL to QTTL transitions. It features a maximum low-level output current of -3 mA and a maximum high-level output current of 24 mA. The component is housed in an 8-pin SOIC package with dimensions of 5 mm x 4 mm x 1.5 mm.

Translators, Level Shifters Feature Summary

• Supports bidirectional voltage level translation between differential ECL standards (PECL, CML, LVDS) and single-ended TTL/CMOS logic.
• Contains two independent unidirectional converter channels within a single integrated circuit.
• Designed for direct interfacing with high-speed digital communication systems requiring mixed-logic compatibility.

Translators, Level Shifters Applications

• Interfacing PECL clock sources with TTL-based microprocessors or memory controllers.
• Level shifting between CML/LVDS data lines and TTL input interfaces.
• Converting TTL control signals to PECL outputs for high-speed peripheral connections.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DG' confirms the lead-free, halogen-free RoHS-compliant variant in the standard 8-SOIC package. Confirm that the required logic family matches the device's capability for both PECL-to-TTL and TTL-to-PECL translation. Ensure the design accommodates the specified 4.75 V to 5.25 V power supply range and thermal requirements for the -40 °C to +85 °C operating temperature span.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between ECL-derived standards and TTL is required in a compact surface-mount form factor. The dual-channel architecture reduces board space compared to using single converters. Consider the propagation delay characteristics if timing margins are critical for the specific transition direction (DTTL to QECL vs. DECL to QTTL).
