Bidirectional I2C Isolators
Texas Instruments Incorporated (Dallas, TX) (NASDAQ: TXN) has introduced a bidirectional isolator family compatible with I2C interfaces. Each of the new integrated circuits (ICs) can replace a typical implementation of 16 or more discrete devices to isolate the I2C signal in industrial applications. Features include:
- A silicon dioxide barrier (SiO2) to separate logic input and output buffers.
- A maximum current of less than 8.5 mA at 5 V.
- A maximum propagation delay of 62 nanoseconds.
- ± 50-kV/us typical transient immunity that provides better reliability in harsh environments.
- Isolated bidirectional communications by employing an offset configuration that prevents device latch-up and ensures reliable operation.
