I
Subject to general operating conditions for V
The STR7 I
protocol described in the following table with the restriction mentioned below:
Restriction: The I/O pins which SDA and SCL are mapped to are not “True” Open-Drain:
when configured as open-drain, the PMOS connected between the I/O pin and V
disabled, but it is still present. Also, there is a protection diode between the I/O pin and V
Consequently, when using this I
the STR7X while some another I
STR7X will be powered by the protection diode.
Refer to I/O port characteristics for more details on the input/output alternate function
characteristics (SDA and SCL).
