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

Ω, 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.
