ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating junction temperature range. VNTC = VCC, TA = 25°C unless otherwise specified. Current into a pin is positive and current out of a pin is negative. All voltages are referenced to GND unless otherwise noted. (Note 2) SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
