PIN TYPE DEFINITIONS
Analog Input — A pin that is used by the analog and is never driven by the device. Supplies are part of this
classification.
Analog Output — A pin that is driven by the device and should not be driven by external sources.
Analog Input/Output — A pin that is typically used for filtering a DC signal within the device. Passive
components can be connected to these pins.
Digital Input — A pin that is used by the digital but is never driven by the device.
Digital Output — A pin that is driven by the device and should not be driven by another device to avoid
contention.
Digital Input/Output — A pin that is either open drain (SDA) or a bidirectional CMOS in/out. In the latter case
the direction is selected by a control register within the LM49350.
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, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All
voltages are measured with respect to the ground pin, unless otherwise specified.
(2)
The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as
otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and
are not ensured.
(3)
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4)
The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature,
TA. The maximum allowable power dissipation is PDMAX = (TJMAX - TA) / θJA or the number given in Absolute Maximum Ratings,
whichever is lower.
(5)
Human body model, applicable std. JESD22-A114C.
(6)
Machine model, applicable std. JESD22-A115-A.
