ISO7241AMDWREP

Overview

The ISO7241AMDWREP is a general-purpose digital isolator from Texas Instruments, featuring four independent channels in a 16-SOIC package. It supports a data rate of 1 Mbps and provides 4000 Vpk isolation voltage with a common-mode transient immunity (CMTI) of 25 kV/µs. The device operates on a supply voltage range of 3.15 V to 5.5 V, drawing 18 mA of operating supply current. Propagation delay is typically 15 ns, with a maximum pulse width distortion of 2.5 ns. It functions within an extended temperature range of -55°C to 125°C.

Feature Summary

• Provides robust galvanic isolation between circuits using capacitive coupling technology.
• Features high common-mode transient immunity for reliable signal transmission in noisy environments.
• Offers quad-channel configuration with unidirectional signal paths for versatile interface applications.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing enhanced safety isolation barriers
• Power electronics monitoring and control circuits

Procurement Notes

Verify the specific suffix 'REP' indicates reel packaging when ordering. Confirm the 1 Mbps speed grade matches system requirements, as other variants offer higher speeds. Ensure the 4000 Vpk isolation rating meets safety standards for the target application. Check lead times due to potential production cycle variations.

Selection Notes

Select this part for applications requiring moderate data rates up to 1 Mbps with high isolation voltage. Compare against ISO7241CDWR if higher speed (25 Mbps) is needed. Consider the -55°C minimum operating temperature for harsh industrial environments. Verify pin compatibility with existing designs using standard SOIC-16 footprints.

Part Context

This component belongs to the ISO7241 family of digital isolators from Texas Instruments. It shares the same physical package and basic functionality as other speed grades like ISO7241MDWR but offers lower bandwidth. The family utilizes capacitive coupling for signal transmission without magnetic components.

Replacement Considerations

ISO7241MDWR offers similar features but with a 150 Mbps data rate. ISO7241CDWR provides 25 Mbps speed. Direct substitutes must maintain 4000 Vpk isolation and 16-SOIC packaging. Verify electrical characteristics match before substitution.
