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 to5.0V. Inputs under test switching: 5.0V to threshold (VILD), 0V to threshold (VIHD), f=1MHz.

CL = 15/50 pF or equivalent (includes jig and probe capacitance)

RT =ZOUT of pulse generator (typically 50

Ω)

WAVEFORM: PROPAGATION DELAYS (f=1MHz; 50% duty cycle)
