These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply

when operating the device beyond its rated operating conditions.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

(3)

Input voltage above V+ is allowed.

(4)

More accurately, it is excessive current flow, with resulting excess heating, that limits the voltages on all pins. When any pin is pulled a

diode drop below V

−, a parasitic NPN transistor turns ON. No latch-up will occur as long as the current through that pin remains below

the Maximum Rating. Operation is undefined and unpredictable when any parasitic diode or transistor is conducting.

(5)

Junction temperature may be calculated using TJ = TA + P D

θjA. The given thermal resistance is worst-case for packages in sockets in

still air. For packages soldered to copper-clad board with dissipation from one comparator or reference output transistor, nominal

θjA is

90°C/W for the DW package.

Typical values in standard typeface are for TJ = 25°C; values in boldface type apply for the full operating temperature range. These

values represent the most likely parametric norm.

All limits are ensured at room temperature (standard type face) or at operating temperature extremes (bold type face).
