This graph shows the percentage of peak pulse power or current that can be applied as a function of ambient temperature (TA) in °C. The curve starts at 100% at 25°C and decreases linearly, reaching approximately 25% at 150°C.
This graph illustrates the input capacitance (CI/O in pF) for I/O to Vss at f=1MHz, plotted against the input voltage (VI/O in V). The capacitance is approximately 0.6pF at 0V and decreases slightly to around 0.5pF as the voltage increases to 5V.
This graph shows the current (A) flowing from I/O to Vss as a function of voltage (V) from I/O to Vss. The current is near zero until approximately 6V, after which it increases sharply, reaching 16A at around 15V.
