ISO7742DBQR Description

Short technical summary and product information.

The Texas Instruments ISO7742DBQR is a reinforced, 4-channel digital isolator with a general-purpose type. It operates over a wide temperature range of -55°C to 125°C and supports a maximum data rate of 100Mbps. The device provides 3000Vrms of isolation, with surge isolation capabilities up to 12.8kVPK and transient isolation up to 8000VPK.

 

Designed for surface mounting, the ISO7742DBQR comes in a 16-SSOP package. Key electrical specifications include a typical propagation delay of 10.7ns and a minimum common-mode transient immunity (CMTI) of 85kV/µs. It supports bidirectional communication with 2 forward and 2 reverse channels and operates with a supply voltage range of 2.25V to 5.5V.

 

This isolator is suitable for applications requiring robust isolation and high electromagnetic compatibility (EMC). It meets certifications from CQC, CSA, DIN, and TUV, offering both basic and reinforced isolation ratings.
