*2: The parameters t
DVSIC
and t
DVHIC
shall be met for lumped capacitive loads of 15 and 40 pf at the IC where all signals have the same
capacitive load value. Noise that may couple onto the output signals from external sources in a normally functioning system has not
been included in these values.
Note:
All timing measurement switching points (low to high and high to low) shall be taken at 1.5V.
