You can also achieve a similar result with ac AC parallel termination (resistor and cap pull down or up) but for limiting the energy the series terminator as close to the source is best. WebbThe I2C bus transmits data and clock with SDA and SCL. The first thing to realize: SDA and SCL are open-drain (also known as open-collector in the TTL world), that is I2C master and slave devices can only drive these lines low or leave them open. The termination resistor Rp pulls the line up to Vcc if no I2C device is pulling it down.
