Electrical Specifications

2.1.1.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the STAC9752/9753. 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 STAC9752/9753 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 STAC9752/9753 implements internal ESD protection circuitry, proper ESD precautions should be followed to

avoid damaging the functionality or performance.
