MC100ELT28DT

Translators, Level Shifters Overview

The MC100ELT28DT is a dual-direction voltage level translator manufactured by onsemi, integrating TTL to differential PECL and differential PECL to TTL conversion within a single package. Designed for backplane signal transmission, it operates with a supply voltage range of 4.75 V to 5.25 V referenced to ground. The device features flow-through pinouts and includes internal PECL input pulldown resistors. It provides 24 mA TTL output drive capability and utilizes PNP inputs for minimal loading. The component is housed in an 8-lead TSSOP package.

Translators, Level Shifters Feature Summary

• Integrates bidirectional translation between TTL and differential PECL logic levels
• Includes internal pull-down resistors on PECL inputs to manage open states
• Features flow-through pinout configuration for simplified circuit layout
• Provides default high output states when inputs are left open or below threshold

Translators, Level Shifters Applications

• Backplane signal transmission systems
• Interfacing TTL logic circuits with PECL components
• Converting differential PECL signals to standard TTL levels

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-8 package variant required for your design. Confirm that the manufacturer's RoHS compliance status aligns with current environmental regulations for your region. Ensure the operating temperature range of -40°C to +85°C meets your system's thermal requirements before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when a compact solution is needed to bridge TTL and PECL domains without separate chips. The integrated design reduces board space compared to discrete translators. Verify that the power supply constraints fit within the specified 4.75 V to 5.25 V window. Consider the propagation delay characteristics if timing margins are critical for your specific data rates.

Translators, Level Shifters Part Context

This part belongs to the MC10EL/100ELT series of voltage level translators from onsemi. The 100 Series designation indicates the inclusion of temperature compensation features for improved performance stability across varying thermal conditions. These devices are part of the broader ECLinPS family designed for high-speed digital interfacing applications.

Translators, Level Shifters Replacement Considerations

MC10ELT28DTG serves as the lead-free equivalent for the MC10ELT28DT. For alternative packages, the SOIC-8 version is designated as MC100ELT28DG.
