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: I
Note 2: I
CC
is defined as the current level where the V
CC
voltage is lower
by 100mV from the value with 2mA of current.
