The power supply lines must be decoupled with a 0.1 μF capacitor placed as close to the device package as
possible (Figure 16). The bypass capacitor should have low effective series resistance (ESR) and low effective
series inductance (ESI), such as the common ceramic types, which provide a low impedance path to ground
at high frequencies to handle transient currents caused by internal logic switching.
Pull-up resistors (Rp) maintain the SDAH and SCLH lines at a high level when the bus is free and ensure the
signals are pulled up from a low to a high level within the required rise time. For a complete description of the
