It is recommended that SDA is delayed from the falling edge of SCL by 0.3 µ s minimum in the S-
24CS01A/02A/04A/08A. This is to prevent time lag caused by the load of the bus line from generating the
stop (or start) condition.
The S-24CS01A/02A/04A/08A 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.
