[1] Unused inputs must be held HIGH or LOW to prevent them from floating.
[2] V_TT maximum of 3.6 V with resistor sized so I_OL maximum is not exceeded.
[3] A0, A1 V_I(max) is 3.6 V if configured as outputs (DIR = L).

[1] All typical values are measured at V_CC = 3.3 V and T_amb = 25 °C.
[2] The input and output voltage ratings my be exceeded if the input and output current ratings are observed.
[3] This is the increase in supply current for each input that is at the specified TTL voltage level rather than V_CC or GND.
