ISO7731DBQR Description

Short technical summary and product information.

The Texas Instruments ISO7731DBQR is a high-speed, robust digital isolator featuring three channels. It supports a 100Mbps data rate and provides 3000Vrms of isolation, with options for up to 5000Vrms.

 

This isolator is suitable for general-purpose applications and operates over a wide temperature range of -55°C to 125°C. Key electrical specifications include a low propagation delay of 11ns typical and a common-mode transient immunity (CMTI) of 85kV/µs minimum. It consumes low power, with a typical current consumption of 1.53mA per channel at 1Mbps.

 

The ISO7731DBQR is available in a 16-SSOP surface-mount package. Its robust isolation barrier offers over 30 years of projected lifetime at 1500VRMS working voltage and includes system-level ESD, EFT, and surge immunity. The device supports GPIO, PWM, and UART protocols.
