ABSOLUTE MAXIMUM RATINGS
RECOMMENDED DC OPERATING CONDITIONS
(TA = -40°C to +85°C, unless otherwise noted.) (Note 2)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Voltage Range on VCC or VBACKUP Pins
Relative to Ground.............................................-0.3V to +6.0V
Voltage Range on Inputs Relative
to Ground ...............................................-0.3V to (VCC + 0.3V)
Junction-to-Ambient Thermal Resistance (
θJA) (Note 1)..170°C/W
Junction-to-Case Thermal Resistance (
θJC) (Note 1) ......40°C/W
Operating Temperature Range
(noncondensing) .............................................-40°C to +85°C
Storage Temperature Range .............................-55°C to +125°C
