Overview
The ISO7241MDWRG4 is a quad-channel digital isolator produced by Texas Instruments. This component is part of the ISO7241x family, which features three channels in the same direction and one channel in the opposite direction. It is designed to provide reliable signal transmission and isolation, making it suitable for a wide range of applications. The device uses Texas Instruments’ silicon-dioxide (SiO2) isolation barrier to block high voltages, isolate grounds, and prevent noise currents from interfering with sensitive circuitry. It operates with 3.3V or 5V supplies on either side and is characterized for operation over a temperature range of –40°C to +125°C.
