It is recommended that SDA is delayed from the falling edge of SCL by 0.3 µ s minimum in the S-
24C04BPHAL. This is to prevent time lag caused by the load of the bus line from generating the stop (or
start) condition.
The S-24C04BPHAL 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 (at room temperature), noise with a pulse width of 150 ns or
less can be suppressed.
