• Manufacturer Part Number: T8531A/T8532
• Description: Multichannel Programmable Codec Chip Set
• Manufacturer: Agere Systems, Inc.

Codec Chip Set
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 section 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. Agere Systems Inc. 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 stan-
dard has been adopted for the CDM. A standard HBM (resistance = 1500
accepted and can be used for comparison. The HBM ESD threshold presented here was obtained by using these
circuit parameters:
