(1) Typical values are given for V_CC = 3.3V and T_A = +25°C.
(2) Current into device pins is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to ground
except VOD, and ΔVOD which are differential voltages.

(1) Typical values are given for V_CC = 3.3V and T_A = +25°C.
(2) Current into device pins is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to ground
except VOD, and ΔVOD which are differential voltages.
(3) t_LLHT, t_LHLT, t_DJIT and t_RJIT specifications are ensured by design using statistical analysis.
