Notes:
1. Exceeding the absolute maximum rating may damage the device
2. The device is not guaranteed to function outside its operating rating
3. This device is ESD sensitive
4. Timing numbers are for a data rate of 1 kbps. Except where shown, all data timing scales linearly with the data rate.
5. In this context, deglitching refers to the D0-D3 pins’ ability to reject high- or low-going glitches. Deglitching makes it much easier to use low-cost
push-to-make switches which have inherently noisy contacts.
6. Guaranteed by design.
