SN65ELT20D

Translators, Level Shifters Overview

The SN65ELT20D is a single-channel voltage level translator manufactured by Texas Instruments, designed to convert signals from 5V TTL logic levels to differential PECL outputs. It operates within a supply voltage range of 4.2 V to 5.7 V and supports data rates up to 860 Mb/s. The device features a propagation delay of 1.25 ns and draws a typical operating supply current of 16 mA. It is housed in an 8-pin SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Converts single-ended 5V TTL inputs to differential PECL outputs for high-speed interface compatibility
• Supports data transmission speeds up to 860 Mb/s with low propagation delay
• Operates on a single 5V power supply without requiring additional negative voltages

Translators, Level Shifters Applications

• Interfacing 5V TTL logic circuits with differential PECL receivers
• Clock distribution systems requiring level translation between different logic families
• High-speed digital communication links utilizing PECL signaling standards

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-8 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accommodates the specified 4.2 V to 5.7 V supply voltage range for reliable operation across the full industrial temperature spectrum.

Translators, Level Shifters Selection Notes

Select this component when interfacing standard 5V TTL sources with differential PECL destinations. It is suitable for applications requiring moderate data rates up to 860 Mb/s. Consider alternative packages such as DGK or DR if surface mount density or tape-and-reel processing is required instead of the tube-packaged SOIC option.

Translators, Level Shifters Part Context

This part belongs to the SN65ELT20 series of voltage translators. It serves as a bridge between single-ended logic families and differential signaling standards. The family includes variants with different packaging options like DGK and DR, maintaining identical electrical functionality while offering flexibility in board layout and manufacturing assembly processes.

Translators, Level Shifters Replacement Considerations

Compatible substitutes include SN65ELT20DR (tape and reel) and SN65ELT20DGK (VSSOP package). These parts share identical electrical specifications and pinouts, allowing for direct replacement based on packaging preference or supply chain availability.
