ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper han-
dling and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may de-
grade device reliability. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those specified is
not implied. (2) Input terminals are diode-clamped to the power-supply rails.
Input signals that can swing more than 0.5V beyond the supply rails should
be current limited to 10mA or less. (3) Short-circuit to ground.

PIN DESCRIPTIONS
NOTE: (1) This pin limits the output current. The limited value, I
LIMIT
, is
9800(I
SET
), where I
SET
is the current flowing through the I
SET
pin. This current
is programmed by the resistor R
SET
connected to V–.
