ISO7421EDR Description

Short technical summary and product information.

The ISO7421EDR from Texas Instruments is a 2-channel digital isolator providing galvanic isolation up to 2500 V RMS. Each 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 a signaling rate greater than 50 Mbps with a typical propagation delay of 7 ns and low pulse skew of 200 ps. It operates from 3-V to 5.5-V supply levels and is suitable for 3.3-V and 5-V level translation. The typical low power consumption is 1.8 mA per channel at 1 Mbps and 2.8 mA at 25 Mbps (3.3-V supplies).

 

Designed for surface mounting, the ISO7421EDR comes in a narrow body SOIC-8 package. It features a wide operating temperature range of -40°C to 125°C and offers 50-KV/μs transient immunity. The isolation barrier life is rated for over 25 years.

 

Safety and regulatory approvals include isolation per DIN V VDE V 0884-10, UL 1577, CSA, IEC 60950-1, and IEC 61010-1 standards, with CQC certification.
