ISO1540QDQ1 Description

Short technical summary and product information.

The Texas Instruments ISO1540QDQ1 is a digital isolator featuring I2C interface support and 2500Vrms isolation. This component utilizes capacitive coupling technology for reliable signal isolation.

 

Key electrical specifications include a maximum data rate of 1Mbps and a high Common Mode Transient Immunity (CMTI) of 25kV/µs. It is designed for bidirectional communication across two channels. The operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface mount configuration, the ISO1540QDQ1 is designed for ease of integration into printed circuit boards. It is not an isolated power device, focusing solely on signal isolation.

 

This digital isolator is compliant with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life under recommended storage conditions. Its REACH status is unaffected.
