operation at the absolute maximum ratings for extended periods of time may have adverse affects on the device.
Minimum DC input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to 4.6 V for
input currents less than 100 mA and periods shorter than 20 ns.
Maximum V
All pins, including dedicated inputs, clock, I/O, and JTAG pins, may be driven before V
powered.
