DUAL OPTICALLY ISO I2C BIDRCTNL REPEATER | Series: I2C-Bus Repeaters
Our Optically Isolated I2C Bus Repeater is the industry's first integrated optical solution for I2C bus design that:
- Minimizes PC board space usage
- Reduces parts count for this function
Unlike magnetically isolated digital isolator ICs, this optical solution:
- Needs no internal clocking, which is a primary source of EMI/RFI interference
- Supports direct static-state buffering without refresh clocks
The CPC5904 features excellent reliability and very long operational life. Contact the factory for long-term reliability information.
