Note 3: Guaranteed by other measured parameters and not tested directly.
Note 4: Time from PS ↑ or ON/OFF ↑ until VDD ≥ 5V and VEE ≤ –5V.
The ● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C, VCC = 1.8V to 5.5V, VL = 1.8V to 5.5V, Normal Mode. Typical values are
given for VCC = VL = 3.3V and TA = 25°C, unless otherwise noted.
Note 1: Absolute maximum ratings are those beyond which the life of a
device may be impaired.
Note 2: All currents into pins are positive; all voltages are referenced to
GND unless otherwise specied.
