ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating

junction temperature range. VNTC = VCC, TJ = 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)
