Cb ; total capacitance of one bus line in pF.
NOTE). Data hold time : tHD:DAT Please hold the Data Hold Time (tHD:DAT) to 300ns or more to avoid status of unstable at SCL falling edge. The SDA block in the NJW1110 does not hold data. Add external data-delay-circuit of the SDA terminal, in case of not providing a hold time of at least 300nsec for the SDA in the master device. The time-consists of the data-delay-circuit of the SDA terminal are as follows. (a) Low level ! High level : (b) High level ! Low level : TLH RP*CD THL RD*CD
In addition, Schottky barrier diode (SBD) influences a Low level at the Acknowledge. Therefore choose the low forward voltage (Vf) as much as possible.
