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 V
DD
≥ 5V and V
EE
≤ –5V.
The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T
A
= 25°C, V
CC
= 1.8V to 5.5V, V
L
= 1.8V to 5.5V, Normal Mode. Typical values are
given for V
CC

L
= 3.3V and T
A
= 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.
