All pins, including dedicated inputs, clock, I/O, and JTAG pins, may be driven before V
powered.
The minimum DC input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to the
voltages shown in
dependent upon duty cycle of the signal. The DC case is equivalent to 100% duty cycle.
This value is specified for normal device operation. The value may vary during power-up. This applies for all V
settings (3.3, 2.5, 1.8, and 1.5 V).
Maximum values depend on the actual T
