MC10ELT28DR2

Translators, Level Shifters Overview

The MC10ELT28DR2G is a dual differential translator integrating TTL to PECL and PECL to TTL conversion within an SOIC-8 package. It operates on a single +5 V supply with GND at 0 V, eliminating the need for negative voltages. The device features flow-through pinouts and internal pull-down resistors. Propagation delays are typically 3.5 ns for PECL to TTL and 1.2 ns for TTL to PECL. It supports a maximum toggle frequency of 100 MHz and includes ESD protection exceeding 2 kV.

Translators, Level Shifters Feature Summary

• Dual-directional translation between TTL and differential PECL logic levels in a single component
• Internal PECL input pull-down resistors ensure stable operation when inputs are left open
• PNP-based TTL inputs minimize loading effects on driving circuits
• Outputs default high if inputs are unconnected or below specified thresholds

Translators, Level Shifters Applications

• Backplane signal transmission and reception
• Interfacing TTL logic devices with PECL systems
• Converting differential PECL signals to standard TTL outputs

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'R2' corresponds to the tape and reel packaging format as documented in the ordering information. Confirm that the part number prefix indicates the 10EL series rather than the temperature-compensated 100EL series. Ensure the selected package matches the required PCB footprint specifications.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level shifting between TTL and PECL is required without external translators. The flow-through pinout simplifies board layout compared to non-flow-through alternatives. Consider the 100EL variant if temperature compensation is necessary for the operating environment.

Translators, Level Shifters Part Context

This device belongs to the MC10ELT/100ELT28 family of voltage level translators. It is designed for applications requiring interface between different logic families using a single positive supply voltage. The family includes variants in both SOIC-8 and TSSOP-8 packages to accommodate different space constraints.

Translators, Level Shifters Replacement Considerations

MC100ELT28DR2G provides equivalent functionality with added temperature compensation.
