ISO7241MDWR

Overview

The ISO7241MDWR is a quad digital isolator from Texas Instruments, utilizing capacitive coupling technology. It features four channels with a 3/1 input-output configuration and supports unidirectional signal transmission. The device operates within a supply voltage range of 3.15V to 5.5V and delivers a data rate of 150Mbps. It provides 2500Vrms isolation voltage and a common-mode transient immunity (CMTI) of 25kV/µs. Maximum propagation delays are 23ns for both low-to-high and high-to-low transitions, with a typical rise/fall time of 2ns. It functions in temperatures from -40°C to 125°C and is housed in a 16-SOIC package.

Feature Summary

• Provides galvanic isolation between circuits using robust capacitive coupling technology.
• Supports high-speed data transmission up to 150Mbps with low pulse width distortion.
• Features high common-mode transient immunity to withstand rapid voltage changes across the isolation barrier.

Applications

• Industrial communication interfaces requiring isolated signal transmission
• Medical equipment needing reliable electrical isolation for safety compliance
• Power electronics systems for gate drive and feedback signal isolation

Procurement Notes

Verify the specific suffix 'MDWR' to confirm the 150Mbps speed grade, SOIC-16 package, and tape-and-reel packaging format. Ensure compatibility with the required 3.15V to 5.5V supply voltage range and check that the 2500Vrms isolation rating meets system safety standards. Confirm the 3/1 channel configuration aligns with the circuit design requirements before procurement.

Selection Notes

Select this component when a quad-channel isolator with 150Mbps performance is needed. It is suitable for applications requiring 2500Vrms isolation and operation up to 125°C. Consider the 16-SOIC package for surface-mount assembly. Compare against other ISO7241 variants if different speed grades or channel configurations are required.
