+3.3 V ± 5%. Power supply pairs for the digital circuitry.
To insure 5 V tolerance in mixed +5 V / +3.3 V systems, this input must be
connected to +5 V. If all logic input signals are 3.3 V levels, then this pin may be
connected to the 3.3 V supply. Bypass with a 10
No-connect pins are reserved for future device compatibility and should be left
unconnected.
