Note 2: All currents into pins are positive; all voltages are referenced to

GND unless otherwise specified.

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 l denotes the specifications which apply over the full operating

temperature range, otherwise specifications 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: 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.
