SN65ELT20DR

Translators, Level Shifters Overview

The SN65ELT20DR is a 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 SOIC-8 surface-mount package and functions reliably across an extended temperature range from -40°C to +85°C.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when ordering. Confirm that the required operating environment falls within the specified -40°C to +85°C temperature range. Ensure the system power supply remains stable between 4.2 V and 5.7 V for proper functionality. Check for any recent Product Change Notifications (PCN) regarding manufacturing updates or material changes.

Translators, Level Shifters Selection Notes

Select this component when interfacing 5V TTL sources with differential PECL loads requiring speeds up to 860 Mb/s. Consider the SOIC-8 package for surface-mount assembly constraints. Evaluate the 16 mA supply current against total system power budgets. Verify compatibility with the 4.2 V to 5.7 V supply voltage window before integration into the design.
