The ISO7421DR from Texas Instruments is a 2-channel digital isolator designed for galvanic isolation up to 2500 V RMS for 1 minute per UL standards. Each isolation channel features a logic input and output buffer separated by a silicon dioxide insulation barrier, preventing noise currents from interfering with sensitive circuitry. This device supports data rates up to 1 Mbps with a typical propagation delay of 9 ns and low skew of 300 ps.
Key electrical characteristics include a typical low power consumption of 1.5 mA per channel at 3.3-V operation and high common mode transient immunity of 50 kV/μs. The ISO7421DR operates from 3.3-V and 5-V supply and logic levels, offering 3.3-V and 5-V level translation. It is suitable for a wide operating temperature range of -40°C to 125°C.
The isolator is supplied in a narrow body SOIC-8 package, suitable for surface mount applications. It meets safety and regulatory approvals including isolation per DIN V VDE V 0884-10 and DIN EN 61010-1, and UL 1577 standards. The device is RoHS3 compliant and has an MSL rating of 1.
