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 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.
