MC100ELT28DG

Translators, Level Shifters Overview

The MC100ELT28DG is a mixed-signal translator providing bidirectional conversion between TTL and differential PECL logic levels within a single package. It features one unidirectional circuit with two channels, housed in an 8-SOIC surface-mount package. The device operates on a +5 V supply (VCC = 4.75 V to 5.25 V) with ground at 0 V. Key electrical parameters include a typical propagation delay of 3.5 ns for PECL-to-TTL translation and 1.2 ns for TTL-to-PECL translation. It incorporates PNP TTL inputs for minimal loading and provides 24 mA TTL output drive capability.

Translators, Level Shifters Feature Summary

• Bidirectional translation between TTL and differential PECL logic levels
• Temperature compensation included in the 100 Series
• Internal PECL input pulldown resistors prevent floating inputs
• Outputs default high when inputs are left open or below threshold

Translators, Level Shifters Applications

• Backplane signal transmission and reception
• Interfacing TTL-based systems with PECL components
• High-speed data communication links requiring level shifting

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific ordering suffix matches the required package type, as the 'DG' suffix denotes the SOIC-8 variant. Ensure compliance with RoHS standards and check for any product change notices regarding manufacturing updates or end-of-life status before finalizing procurement plans.

Translators, Level Shifters Selection Notes

Select this component when interfacing TTL logic with differential PECL circuits in a compact form factor. The 100 Series is preferred over the 10 Series for designs requiring temperature compensation to maintain performance stability across varying thermal conditions. Verify that the system power supply remains within the specified 4.75 V to 5.25 V range to ensure correct operation.
