6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MINMAXUNIT
Supply voltage7V
Signal input terminalsVoltage(2)(V–) – 0.5(V+) + 0.5V
Current(2)±10mA
Output short circuit(3)ContinuousmA
TemperatureOperating, TA–55150°C
Junction, TJ150
Storage, Tstg–65150
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less.
(3) Short-circuit to ground, one comparator per package.

6.2 ESD Ratings

VALUEUNIT
V(ESD)Electrostatic dischargeHuman body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1)±2500V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2)±1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
