ISOW7842FDWER

Overview

The ISOW7842FDWER is a quad-channel reinforced digital isolator manufactured by Texas Instruments. It features a 2/2 channel configuration with unidirectional signal flow and supports data rates up to 100 Mb/s. The device provides an insulation voltage of 5000 Vrms and utilizes both capacitive and magnetic coupling technologies. Operating within a supply voltage range of 3 V to 5.5 V, it exhibits a typical propagation delay of 13 ns and pulse width distortion of 600 ps. The component operates reliably across a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC package.

Feature Summary

• Integrates high-voltage isolation capabilities using combined capacitive and magnetic coupling mechanisms for enhanced reliability.
• Provides four independent unidirectional channels configured as two forward and two reverse paths.
• Features integrated power supply architecture to simplify system design and reduce external component count.

Applications

• Industrial automation systems requiring robust galvanic isolation
• Medical equipment demanding reinforced safety barriers
• Power electronics interfaces for motor control applications

Procurement Notes

Verify the specific suffix FDWER against official Texas Instruments documentation to confirm the SOIC-16 package type and reel packaging configuration. Ensure compatibility with moisture sensitivity level requirements during storage and handling. Cross-reference the manufacturer part number directly with authorized distributors to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a quad-channel solution with integrated power is required for reinforced isolation applications. Compare performance metrics such as common-mode transient immunity and propagation delay against alternative isolators. Consider the thermal dissipation characteristics and operating temperature range relative to the target environment constraints.

Part Context

This device belongs to the ISOW784x family of high-voltage digital isolators from Texas Instruments. The series is designed to replace traditional optocouplers in applications requiring higher reliability and lower power consumption. The ISOW7842 variant specifically addresses needs for multi-channel communication with integrated power conversion capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers include ISOW7842DWE and ISOW7842FDWE. Verify pinout compatibility and electrical specifications before substituting these variants.
