NOTES
1. All voltages are referenced to ground.
2. I/O pins of fast mode devices must not obstruct the SDA and SCL lines if V

5. A fast mode device can be used in a standard mode system, but the requirement t SU:DAT > 250ns
6. After this period, the first clock pulse is generated.
7. The maximum t HD:DAT has only to be met if the device does not stretch the LOW period (t LOW ) of
8. C B – Total capacitance of one bus line in picofarads, timing referenced to (0.9)(V
9. Absolute linearity is used to measure expected wiper voltage as determined by wiper position.
10. Relative linearity is used to determine the change of wiper voltage between two adjacent wiper
