I haven't been able to figure this out from the datasheet, please help me by filling in the (?):
for +Vs = 5v and -Vs = 0v, PD pin VIL=1.7v, VIH=3.0v,
for +Vs = 5v and -Vs = -5v, PD pin VIL=1.8v, VIH=3.2v,
for +Vs = 2.5v and -Vs = -2.5v, PD pin VIL=?, VIH=?
Should I still be able to connect PD to +Vs to power up the part, and to ground to power down?
