It is recommended that SDA is delayed from the falling edge of SCL by 0.3 µ s minimum in the S-24CS64A.
This is to prevent time lag caused by the load of the bus line from generating the stop (or start) condition.
The S-24CS64A includes a built-in low-pass filter to suppress noise at the SDA and SCL pins. This means
that if the power supply voltage is 5.0 V, noise with a pulse width of 160 ns or less can be suppressed.
