ELECTRICAL CHARACTERISTICS The ● denotes specifications which apply over the full operating
temperature range, otherwise specifications are TA = 25°C. VCC = 5V, 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 device pins are positive; all currents out of device
pins are negative. All voltages are referenced to ground unless otherwise
specified.
Note 3: An internal Zener clamped the GATE pin to a typical voltage of
12V. External overdrive of the GATE pin beyond the internal Zener voltage
may damage the device. Without a limiting resistor, the GATE capacitance
must be <0.15µF at maximum VCC.
