The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. PVCC = VCC = 5V, VL = VL2 = 3.3V, VIN = GND = GND2 = 0V, ON = VL, and
ON2 = VL2 unless otherwise noted. Specifications apply to all options unless otherwise noted.
TA = 25°C.
