Note 1:
These levels are tested dynamically using a limited amount of functional test patterns, please refer to AC Test Load.
Note 2:
Limited functional test patterns are performed at these input levels. The majority of functional tests are performed at levels of 0V and 3V.
Note 3:
This is measured with a 0.1
m
F bypass capacitor between V
CC
and GND.
Note 4:
The low drive CMOS compatible V
OH
and V
OL
limits are not tested directly. Detailed device characterization validates that this specification can be
guaranteed by testing the high drive TTL compatible V
OL
and V
OH
specification.
