Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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. ESD voltage
thresholds are dependent on the circuit parameters used to define the model. 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. The HBM ESD threshold presented here was obtained by using these cir-
cuit parameters.

Mounting and Connections
Certain precautions must be taken when using solder. For installation using a constant temperature solder, temper-
atures of under 300 °C may be employed for periods of time up to 5 seconds, maximum. For installation with a sol-
dering 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. This device is supplied with solder on the
back of the package. For optimum performance, it is recommended to solder the back of the package to ground.
