IDT821064 QUAD PROGRAMMABLE PCM CODEC WITH GCI INTERFACE
Analog Interface
ABSOLUTE MAXIMUM RATINGS
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation of the device
at these or any other conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect reliability.
