DYNAMIC SWITCHING CHARACTERISTICS
1) Worst case package.
2) Max number of outputs defined as (n). Data inputs are driven 0V to 5.0V, (n-1) outputs switching and one output at GND.
3) Max number of data inputs (n) switching. (n-1) switching 0V to 5.0V. Inputs under test switching: 5.0V to threshold (VILD), 0V to threshold
(VIHD), f=1MHz.
TEST CIRCUIT
CL = 15/50 pF or equivalent (includes jig and probe capacitance)
RL =R1 = 1KΩ or equivalent
RT =ZOUT of pulse generator (typically 50Ω)
