MC10ELT28DTR2

Translators, Level Shifters Overview

The MC10ELT28DTR2G is a dual-directional translator integrating a differential PECL to TTL converter and a TTL to differential PECL converter within a single package. Designed for +5 V operation, it facilitates signal exchange across backplanes using only positive supply voltage and ground. The device features flow-through pinouts and includes internal pull-down resistors on the PECL inputs. It supports operating temperatures from -40°C to +85°C and provides ESD protection exceeding 2 kV via the Human Body Model.

Translators, Level Shifters Feature Summary

• Integrates bidirectional translation between TTL logic levels and differential PECL signals in one component
• Utilizes PNP-type inputs for TTL data lines to minimize loading on driving circuits
• Outputs default to high state when inputs are left open or below specified thresholds
• Incorporates internal pull-down resistors on PECL input pins to stabilize undefined states

Translators, Level Shifters Applications

• Backplane signal transmission and reception
• Interfacing TTL-based systems with PECL networks
• Converting differential PECL clock signals to single-ended TTL formats

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix 'R2' corresponds to tape and reel packaging rather than tube configuration. Confirm the specific suffix indicates the TSSOP-8 package variant. Ensure the part number explicitly includes the 'G' designation to verify lead-free and RoHS compliance status before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when a compact solution is required to bridge TTL and differential PECL domains without separate translator chips. The flow-through pinout simplifies PCB layout compared to non-flow designs. Consider the 100 series variant if temperature compensation is necessary for the application environment.

Translators, Level Shifters Part Context

This device belongs to the MC10ELT/100ELT family of translators manufactured by onsemi. It serves as a specialized interface component within the broader portfolio of ECLinPS logic products. The ELT28 specifically addresses the need for simultaneous conversion in both directions, distinguishing it from unidirectional translator models.

Translators, Level Shifters FAQ

What happens to the outputs if the inputs are left open?

Both the QTTL and QECL outputs will default to a high state when their respective inputs are left open or fall below the specified voltage threshold.

Does the device require negative voltage supplies?

No, because it utilizes PECL levels, the device operates exclusively with a +5 V supply and ground connection.
