Overview
The ISO7742FQDWQ1 is an automotive-grade, quad-channel digital isolator from Texas Instruments, designed for robust electromagnetic compatibility. It features four independent channels with a 2/2 channel configuration in a 16-pin SOIC package. The device supports data rates up to 100 Mb/s and provides reinforced isolation with an insulation voltage of 5000 Vrms. It operates within a temperature range of -40°C to +125°C and draws a typical supply current of 13.4 mA. Propagation delay is specified at 10.7 ns, ensuring high-speed signal integrity in demanding automotive environments.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for Grade 1 temperature operation
- Robust electromagnetic compatibility design suitable for noisy automotive electrical systems
- Quad-channel architecture providing four isolated bidirectional or unidirectional paths
Applications
- Automotive gateway modules requiring multi-channel signal isolation
- In-vehicle network interfaces such as CAN and LIN transceivers
- Battery management systems (BMS) for cell monitoring isolation
Procurement Notes
Verify the specific suffix 'F' indicates tube packaging when ordering, distinct from the 'R' reel variant. Confirm AEC-Q100 Grade 1 certification matches system thermal requirements. Ensure the 16-SOIC footprint aligns with PCB layout constraints. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.
Selection Notes
Select this component for applications requiring four isolated channels with high CMTI performance. Compare against ISO7742 variants based on required packaging type, noting that the 'F' suffix denotes tube packing while 'R' denotes tape and reel. Evaluate power consumption against system thermal budgets given the 13.4 mA operating current. Ensure the 5000 Vrms insulation rating meets safety standards for the specific application voltage levels.
Part Context
This part belongs to the ISO7742-Q1 family of automotive digital isolators. It utilizes capacitive coupling technology to provide galvanic isolation between circuits. The series is engineered to withstand harsh automotive electrical transients and offers a compact solution for space-constrained electronic control units.
Replacement Considerations
ISO7742QDWRQ1: Identical electrical specifications but differs in packaging; uses tape-and-reel instead of tube.
FAQ
