CHARACTERISTICS
Absolute Maximum Ratings†
VDD................................................................................... 7.0V
All Inputs and Outputs w.r.t. VSS ............... -0.3 to (VDD+0.3)V
Maximum Junction Temperature, TJ ............ Internally Limited
Storage temperature .....................................-65°C to +150°C
ESD protection on all pins:

† Notice: Stresses above those listed under
“Maximum Ratings” may cause permanent damage to
the device. This is a stress rating only and functional
operation of the device at those or any other
conditions above those indicated in the operational
listings of this specification is not implied. Exposure to
maximum rating conditions for extended periods may
affect device reliability.
DC CHARACTERISTICS
Electrical Specifications: Unless otherwise indicated, all limits apply for VDD= [VREG(typ.) + 0.3V] to 6V, TA = -40°C to +85°C.
Typical values are at +25°C, VDD = [VREG (typ.) + 1.0V]
