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 device may occur. Operating Ratings indicate conditions for
which the device is functional but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical
specifications under particular test conditions which guarantee specific performance limits. This assumes that the device is within the
Operating Ratings. Specifications are not guaranteed for parameters where no limit is given, however, the typical value is a good
indication of device performance.
(2) If the product is in shutdown mode and V
DD
exceeds 6V (to a max of 8V V
DD
) then most of the excess current will flow through the ESD
protection circuits. If the source impedance limits the current to a max of 10ma then the part will be protected. If the part is enabled
when V
DD
is above 6V circuit performance will be curtailed or the part may be permanently damaged.
(3) The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
, θ
JA
, and the ambient temperature,
T
A
. The maximum allowable power dissipation is P
DMAX
= (T

whichever is lower. For the LM4910, see power derating currents for more information.
(4) Human body model, 100pF discharged through a 1.5k Ω resistor, Pin 6 to ground.
(5) Human body model, 100pF discharged through a 1.5k Ω resistor.
(6) Machine Model, 220pF-240pF discharged through all pins.
