The voltage on any input or I/O pin cannot exceed the power pin during power-up.
T
Input signals switch from 0V to 3V with a rise/fall time of less than 3 ns, clocks and clock enables switch at maximum frequency 20 MHz, while data inputs switch
at 10 MHz. Outputs are unloaded. Icc1(typical) = (20 mA + (freq – 20 MHz)*(0.7 mA/MHz)).
All inputs = V
Tested initially and after any design or process changes that may affect these parameters.
