Soldering Information

(1)

All voltages are measured with respect to the relevant VSS pin unless otherwise specified. All grounds should be coupled as close as

possible to the device.

(2)

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 ensure specific performance limits.Characteristics state DC and AC electrical specifications

under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings.

Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device

performance.

(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 de-rated 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: 100pF discharged through a 1.5k

Ω resistor.

(6)

Machine model: 220pF – 240pF discharged through all pins.
