Notes : 1. GON is measured with V3 varying from 150mV to 350mV (Pin 5 is grounded)
2. GOFF is measured with V5 varying from 150mV to 350mV (Pin 3 is grounded)
3. When the remote input goes from HIGH to LOW the BU508 is switched off and it remains in this condition for the time tdr.
4. The sense input voltage VS is internally limited and results in a limited positive output current Ip0 = g VS limit. Note that due to
the storage time tS of the BU508 limiting of VS leads to a reduced base current of the BU508 and the output current I0 is going to
the positive quiescent current IO0.
