(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground
except V_ID, V_OD, V_TH, V_TL, and ΔV_OD. V_OD has a value and direction. Positive direction means OUT+ is a more positive voltage than
OUT−.
(2) All typical are given for V_CC = +3.3V and T_A = +25°C, unless otherwise stated.
(3) Output short circuit current (I_OS) is specified as magnitude only, minus sign indicates direction only.
(4) The parameters are specified by design. The limits are based on statistical analysis of the device performance over the PVT (process,
voltage and temperature) range.
