SNOSC21C –MAY 1998–REVISED MARCH 2013 www.ti.com
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 DθjA. 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.
(6) Human body model, 100 pF discharged through a 1.5 kΩ resistor.

(1) 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.
(2) All limits are ensured at room temperature (standard type face) or at operating temperature extremes (bold type face).
