This load condition approximates the gate load of a 1200 V/75 A IGBT.
Pulse width distortion (PWD) is defined as |tPHL-tPLH| for any given device.
The difference between tPHL and tPLH between any two VO3120 parts under the same test condition.

Notes
(1)
Pins 1 and 4 need to be connected to LED common.
Common mode transient immunity in the high state is the maximum tolerable |dVCM/dt| of the common mode pulse, VCM, to assure that the
output will remain in the high state (i.e., VO > 15 V).
Common mode transient immunity in a low state is the maximum tolerable |dVCM/dt| of the common mode pulse, VCM, to assure that the
output will remain in a low state (i.e., VO < 1 V).
