NOTES:
1. All voltages are referenced to ground.
2. 8.05KHz is obtained from a –66MHz std part
3. PDN is a power down signal applied to either CTRL0 or CTRL1 pins as appropriate
4. Output voltage swings may be impaired at high frequencies combined with high output loading
5. After this period, the first clock pulse is generated.
6. A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the VIH
MIN of the SCL signal) in order to bridge the undefined region of the falling edge of SCL.
7. The maximum tHD:DAT has only to be met if the device does not stretch the LOW period (tLOW) of the
SCL signal.
