概要
Description
Key features include:
- Quad-channel isolation (configurable as 3 forward + 1 reverse or 4 forward channels).
- Wide supply range (2.25V to 5.5V), enabling compatibility with various logic levels.
- High CMTI (100 kV/µs) for noise immunity.
- AEC-Q100 qualified for automotive use.
Packaged in a 16-pin SSOP (DBQR), it suits space-constrained designs. The ISO7742DBQR is ideal for isolating SPI, I²C, or UART interfaces in systems requiring safety and reliability, such as motor drives, PLCs, or EV chargers.
For more details, refer to the [datasheet](https://www.ti.com/lit/ds/symlink/iso7742.pdf).

- Package: 16-pin SSOP (DBQR) for compact designs.
Ideal for industrial, automotive, and medical applications requiring reliable signal isolation.
Pinout
Pin Count: 16 pins
Functions:
- Provides 4 independent isolation channels (configurable as 3 forward and 1 reverse or 2 forward and 2 reverse).
- Supports high-speed data transmission (up to 100 Mbps).
- Reinforced isolation (up to 5000 Vrms) for safety compliance.
- Wide supply voltage range (2.25V to 5.5V) for compatibility with different logic levels.
- Default output states (high or low) for fail-safe operation.
Common applications include industrial automation, motor control, and isolated communication interfaces.
Application
1. Industrial Automation – Isolating PLCs, motor drives, and sensors.
2. Medical Equipment – Ensuring patient safety in diagnostic and monitoring devices.
3. Renewable Energy – Protecting inverters and battery management systems.
