Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent or latent damage to the device. These
are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Handling Precautions
Although protection circuitry has been designed into this device, proper precautions should be taken to avoid expo-
sure to electrostatic discharge (ESD) during handling and mounting. Lucent employs a human-body model (HBM)
and a charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. No industry-
wide standard has been adopted for the CDM. However, a standard HBM (resistance = 1500
, capacitance =
100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD threshold presented
here was obtained by using these circuit parameters.

Mounting and Connections
Certain precautions must be taken when using solder. For installation using a constant temperature solder, tem-
peratures of under 300 °C may be employed for periods of time up to 5 seconds, maximum. For installation with a
soldering iron (battery operated or nonswitching only), the soldering tip temperature should not be greater than
300 °C and the soldering time for each lead must not exceed 5 seconds.
