2. CHARACTERISTICS AND SPECIFICATIONS
2.1. Electrical Specifications
2.1.1. Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the STAC9766/9767. These ratings, which are standard
values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the
recommended operating temperature range.

ESD: The STAC9766/9767 is an ESD (electrostatic discharge) sensitive device. The human body and test equipment can
accumulate and discharge electrostatic charges up to 4000 Volts without detection. Even though the STAC9766/9767
implements internal ESD protection circuitry, proper ESD precautions should be followed to avoid damaging the functionality
or performance.
