ELECTRICAL CHARACTERISTICS
ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute
maximum ratings are stress ratings only and functional device operation is not implied.
VDD, VCC5 ................................................................................................................................................................. 6.0V
VSS, GND ............................................................................................................................................................. 0 ± 0.3V
Junction Temperature............................................................................................................................................... 150°C
Storage Temperature Range ...................................................................................................................... -65°C to 150°C
Lead Temperature (Soldering, 10s).......................................................................................................................... 260°C
OPERATING CONDITIONS
Normal Temperature Range ......................................................................................................................... -10°C to 60°C
VCC5 Range ...................................................................................................................................................2.7V to 4.5V
Thermal Resistance (θJA)..................................................................................................................................... 100°C/W
VDD Range (VCC5 ≥ VDD).............................................................................................................................2.7V to 4.5V
Unless otherwise specified, VCC5 & VDD = 2.7V to 3.8V, TA = Operating Temperature Range (Note 1) 6.144 or
