ISO7341CDW

Overview

The ISO7341CDW is a quad-channel digital isolator manufactured by Texas Instruments, housed in a 16-SOIC package. It provides 3000Vrms isolation voltage and supports data rates up to 25Mbps with a common-mode transient immunity of 25kV/µs. The device operates on a supply voltage range of 3V to 5.5V and features a 3/1 channel configuration (three inputs on one side, one on the other). It functions within an operating temperature range of -40°C to 125°C.

Feature Summary

• Provides robust galvanic isolation for digital signal transmission between circuits.
• Features high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports low-power operation suitable for energy-efficient system designs.

Applications

• Industrial automation systems requiring isolated communication interfaces.
• Medical equipment needing safe patient isolation barriers.
• Power electronics control circuits for motor drives and inverters.

Procurement Notes

Verify the specific suffix 'DW' confirms the 16-SOIC package variant. Confirm RoHS compliance status matches current manufacturing standards. Check datasheet revision history for any pinout or electrical parameter updates before finalizing integration into production designs.

Selection Notes

Select this component when four independent isolated channels are required in a single package. Ensure the 3000Vrms isolation rating meets safety standards for the application. Verify that the 25Mbps data rate is sufficient for the target communication protocol speed requirements.

Part Context

This part belongs to the ISO734x family of robust, low-power quad-channel digital isolators from Texas Instruments. These devices utilize capacitive coupling technology to transmit signals across isolation barriers while maintaining high reliability and EMC performance in demanding industrial applications.

Replacement Considerations

Check for ISO7341CDWR as a reel-packaged alternative from the same manufacturer. Verify compatibility with other ISO734x variants if pinout and electrical specifications match exactly.

FAQ
