ISO7820LLDW

Overview

The ISO7820LLDW is a high-performance, reinforced isolated dual-LVDS buffer manufactured by Texas Instruments. It operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 100 Mb/s. The device features capacitive coupling isolation with an insulation voltage rating of 5700 Vrms. It exhibits a typical propagation delay of 17 ns and consumes 14.2 mA of operating supply current. The component is housed in a SOIC-16 package and functions unidirectionally without shutdown capabilities.

Feature Summary

• Provides reinforced isolation for LVDS signal transmission between circuits
• Utilizes capacitive coupling technology for signal integrity
• Supports high-speed data communication at rates up to 100 Mb/s

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power electronics control interfaces

Procurement Notes

Verify the specific suffix 'DW' indicates the tube packaging format when ordering. Confirm that the 'LL' designation aligns with the required reinforced isolation ratings for your application standards. Ensure the SOIC-16 footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to confirm compatibility with your design specifications.

Selection Notes

Select this component when reinforced isolation is mandated by safety standards rather than basic isolation. Compare power consumption against other isolators if battery life is critical. Verify that the LVDS output interface matches the receiver input requirements. Consider the thermal performance of the SOIC-16 package under continuous operation conditions.
