3. CHARACTERISTICS
3.1. Electrical Specifications
3.1.1. Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 92HD99. These rat-
ings, 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 sec-
tions 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 92HD99 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 92HD99 implements
internal ESD protection circuitry, proper ESD precautions should be followed to avoid damaging the functionality or
performance.
