Absolute Maximum Ratings

Voltage Range on VCC Pin Relative to Ground....-0.3V to +6.0V

Operating Temperature Range (Noncondensing)

Commercial.........................................................0°C to +70°C

Industrial.......................................................... -40°C to +85°C

Storage Temperature Range

EDIP................................................................ -40°C to +85°C

PDIP, SO, TSOP............................................ -55°C to +125°C

Lead Temperature (soldering, 10s).................................. +260°C

(Note: EDIP is hand or wave-soldered only.)

Soldering Temperature (reflow)........................................+260°C

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.

DC Electrical Characteristics

(VCC = +4.5V to +5.5V, or VCC = +2.7V to +3.7V, TA = Over the operating temperature range, unless otherwise noted. Typical

values are with TA = +25°C, VCC = 5.0V or 3.0V and VBAT = 3.0V, unless otherwise noted.) (Note 2)
