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.

Notes: 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 capacitance expected in the actual system.
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 either VCCQ or VSS. ISB might be slightly higher for up to 500ms after power-up, or when entering
standby mode.
