† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values are with respect to the network ground terminal.

3. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace

length of zero.

‡ Typical values are at TA = 25°C.

§ This is the lowest voltage at which RESET becomes active, VCC slew rate ≤ 5 V/µs.
