On high-to-low transitions, output T
VALID
values increase/decrease by 23 ps for each increase/decrease of 1pF.
On low-to-high transitions, output T
VALID
values increase/decrease by 20 ps for each increase/decrease of 1pF.
2
On high-to-low transitions, output T
VALID
values increase/decrease by 16 ps for each increase/decrease of 1pF.
On low-to-high transitions, output T
VALID
values increase/decrease by 20 ps for each increase/decrease of 1pF.
On high-to-low transitions, the slew rate at 50 pF loading is 1.93 V/ns typical; .94 V/ns worst case.
On low-to-high transitions, the slew rate at 50 pF loading is 1.15 V/ns typical; .70 V/ns worst case.
