ELECTRICAL CHARACTERISTICS
Table 9: Absolute Maximum Ratings
Stresses greater than those listed may cause permanent damage to the device. This is a stress rating only, and functional 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.
Table 10: Electrical Characteristics and Operating Conditions
Wireless Temperature (-30°C < T
Note:
1. Input signals may overshoot to VCCQ + 1.0V for periods less than 2ns during transitions.
2. Input signals may undershoot to VSS - 1.0V for periods less than 2ns during transitions.
3. BCR[5:4] = 01b (default setting of one-half drive strength).
4. This parameter is specified with the outputs disabled to avoid external loading effects. The user must add the current required to drive output
5. ISB (max) values measured with PAR set to FULL ARRAY and at +85°C. In order to achieve low standby current, all inputs must be driven to
6. ISB (typ) is the average ISB at 25°C and VCC = VCCQ = 1.8V. This parameter is verified during characterization, and is not 100% tested.
