1 Typical data was characterized at 5.0 V, 25°C or is recommended value.

2 The input clock source must be divided using RDIV to within the range of 31.25 kHz to 39.0625 kHz.

3 This parameter is characterized and not tested on each device. Proper PC board layout procedures must be followed to achieve

specifications.
