Test Conditions
V_OUT = 0V
V_IN = 0V
Notes: (1) V_IL min. and V_IH max. are for reference only and are not tested.
(2) This parameter is periodically sampled and not 100% tested.
(3) t_PUR and t_PUW are the delays required from the time V_CC is stable until the specified operation can be initiated. These parameters
are periodically sampled and not 100% tested.
