(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress

ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under

Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device

reliability.

(2)

TJ = TA as a result of the low dissipated power in this device.

(3)

The absolute maximum rating is VDD + 0.3 V or 7.0 V, whichever is smaller.

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with

less than 500-V HBM is possible with the necessary precautions.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with

less than 250-V CDM is possible with the necessary precautions.

Using a CCRST capacitor of 0.1 nF or 1000 nF gives a reset delay of 703 µs or 3.22 seconds, respectively.

(2)

Using a CCWD capacitor of 0.1 nF or 1000 nF gives a tWDU(typ) of 62.74 ms or 77.45 seconds, respectively.
