Summary:
The Texas Instruments ISO7321CQDQ1 is a 2-channel digital isolator designed for automotive applications. It offers robust isolation and high signaling rates in a compact package.

Description:
The ISO7321CQDQ1 from Texas Instruments is a 2-channel digital isolator, qualified for automotive applications and AEC-Q100 compliant. It provides galvanic isolation up to 3000 V RMS for 1 minute per UL 1577 and 4242 V PK per VDE V 0884-10.

Key electrical specifications include a signaling rate of 25 Mbps and a typical propagation delay of 33 ns. The device features integrated noise filtering on the inputs and supports 3.3-V and 5-V level translation. It offers low power consumption, with typical ICC per channel at 1 Mbps being 1.7 mA for 5-V supplies and 1.2 mA for 3.3-V supplies. Transient immunity is rated at 65 kV/μs typical.

This digital isolator operates within an ambient temperature range of -40°C to 125°C and has an isolation barrier life exceeding 25 years. It is housed in a narrow body SOIC-8 package, suitable for surface mount applications. The ISO7321CQDQ1 also boasts robust electromagnetic compatibility (EMC) with system-level ESD, EFT, and surge immunity, along with low emissions.
