ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at 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 current into device pins are positive; all current out of device
pins are negative; all voltages are referenced to ground unless otherwise
specified.
Note 3: An internal Zener at the GATE pin clamps the charge pump voltage
to a typical maximum operating voltage of 26V. External voltage applied to
the GATE pin beyond the internal Zener voltage may damage the part. If a
lower GATE pin voltage is desired, use an external Zener diode. The GATE
capacitance must be < 0.15μF at maximum VCC.
