Maxim Integrated
DS1340
ABSOLUTE MAXIMUM RATINGS
RECOMMENDED DC OPERATING CONDITIONS
(VCC = VCC MIN to VCC MAX, TA = -40掳C to +85掳C, unless otherwise noted. Typical values are at VCC = 3.3V, TA = +25掳C, unless
otherwise noted.) (Note 1)
Stresses beyond those listed under 鈥淎bsolute Maximum Ratings鈥� 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 SDA, SCL, and FT/OUT
Relative to Ground..................................-0.3V to (VCC + 0.3V)
Operating Temperature Range ...........................-40掳C to +85掳C
Storage Temperature Range .............................-55掳C to +125掳C
Lead Temperature (soldering, 10s) .................................+260掳C
Soldering Temperature (reflow) .......................................+260掳C
