(1) “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to
imply that the device should be operated at these limits. “Electrical Characteristics” specify conditions for device operation.
(2) Typical values are given for V_CC = 3.3V and T_A = +25°C.
(3) V_OS previously referred as V_CM.
(4) Current into device pins is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to ground
unless otherwise specified (except V_OD and ΔV_OD).
