Table 9.1 Absolute Maximum Ratings

If devices are stored out of the packaging beyond this time limit the devices should be baked

before use. The devices should be ramped up to a temperature of 125°C and baked for up to 17

hours.

** The drive strength of the output stage may be configured for either 4mA, 8mA, 12mA or 16mA

depending on the register setting controlled within the firmware. The default is 4mA.
