and t
PLH
between any two HCPL-3140 parts under the same test condition.
5. Common mode transient immunity in the high state is the maximum tolerable dV
CM
/dt of the common mode pulse, V
CM
, to assure
that the output will remain in the high state (i.e., V
O
> 15.0 V).
6. Common mode transient immunity in a low state is the maximum tolerable dV
CM
/dt of the common mode pulse, V
CM
, to assure that
the output will remain in a low state (i.e., V
O
< 1.0 V).
