The SDA block in the NJW1151 does not hold data. Add external data-delay-circuit of the SDA terminal, in case of not
The time-consists of the data-delay-circuit of the SDA terminal are as follows.
In addition, Schottky barrier diode (SBD) influences a Low level at the Acknowledge. Therefore choose the low forward
