† 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.

NOTE 1: Voltage values are with respect to GND, and all GND terminals should be routed to minimize inductance to system ground.

NOTES:

2. VCC is selected by JTAG test system interface requirements.

3. The algebraic convention, where the more negative (less positive) limit is designated as a minimum, is used for logic-voltage levels

only.
