DC Voltage applied to any Pin can be . . VSS -0.5 V to
VDD +0.5 V
Stresses above those listed under ABSOLUTE MAXI-
MUM RATINGS may cause permanent device failure.
Functionality at or above these limits is not implied or
recommended. Exposure to Absolute Maximum
Ratings for extended periods may affect device reliabil-
ity. Programming conditions may differ.
OPERATING RANGES
Commercial (C) Devices
Temperature (TA) . . . . . . . . . . . . . . . . . .0

Supply Voltages (VDDIO, VDD, VDDTX) . . . . . +5 V ±5%
Supply Voltages (VDDIO) . . . . . . . . . . . . . . +3.3 V ±5%
Operating ranges define those limits between which
the functionality of the device is guaranteed.
