4 When to Use TXG vs. Galvanic Isolation

TXG devices are recommended when ground mismatch exists but galvanic isolation is not required. They provide low latency, high-speed signaling, and cost-effective robustness for automotive interfaces such as I2C, SPI, UART, and GPIO.

• Use TXG when galvanic isolation is not needed but ground mismatch is a concern.
• Use TXG for low-voltage (upto 80V) static or dynamic immunity (CMTI 1kV/μs).
• Use ISO to break current loops and for safety applications.
