SSR-25LA-H - ANV

SSR-25LA-H SSR Series SOLID STATE RELAY

The MCP79410 is an I2C slave device. SDA is a bidirectional pin used to transfer data in and out of the device. It is an open-drain terminal, therefore, the SDA bus requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz and 2 kΩ for 400 kHz). For normal data transfers, SDA is allowed to change only during SCL low. Changes during SCL high are reserve.
