Notes
1. Two ceramic multilayer capacitors of minimum 100 nF with low ESR should be used in order to meet these
specifications.
2. Pin I/O1 has an internal 14 k
pull-up resistor to VCC1 and pin I/O2 has an internal 14 k pull-up resistor to VCC2.
3. Pins I/O1uC and I/O2uC have an internal 11 k
pull-up resistor to VDDI.
4. The hold time required (not greater than 300 ns) to bridge the undefined region of the falling edge of SCL must be
internally provided by a transmitter.
