ELECTRICAL CHARACTERISTICS The ● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. VCC = 3.3V, Vn = 0.55V, SEL = VCC, DIS = OPEN unless otherwise noted.
(Note 2)
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All currents into pins are positive; all voltages are referenced to
GND unless otherwise noted.
Note 3: VCC maximum pin voltage is limited by input current. Since the
VCC pin has an internal 6.5V shunt regulator, a low impedance supply that
exceeds 6V may exceed the rated terminal current. Operation from higher
voltage supplies requires a series dropping resistor. See Applications
Information.
