2. This value is limited to 7V maximum.

3. The package thermal impedance is calculated in accordance with JESD

51.

Notes:

Stresses greater than those listed under MAXIMUM RATINGS may cause

permanent damage to the device. This is a stress rating only and func-

tional operation of the device at these or any other conditions above those

indicated in the operational sections of this specification is not implied.

Exposure to absolute maximum rating conditions for extended periods

may affect reliability.

Recommended Operating Conditions for VCCA = 4.5V to 5.5V(4)

Notes: 4. All unused inputs of the device must be held at the associated VCC or GND to ensure proper device operation.

Recommended Operating Conditions for VCCB = 2.7V to 3.6V(4)

Notes: 4. All unused inputs of the device must be held at the associated VCC or GND to ensure proper device operation.
