Static common-mode transient immunity (CMTI) is defined as the largest dv/dt between GND
1
and GND
2
, with inputs held either high or low, such that the output
voltage remains either above 0.8 × V
DD2
for output high or 0.8 V for output low. Operation with transients above recommended levels can cause momentary data upsets.
7
Dynamic common-mode transient immunity (CMTI) is defined as the largest dv/dt between GND
1
and GND
2
with the switching edge coincident with the transient test
pulse. Operation with transients above the recommended levels can cause momentary data upsets.
