1. All specified voltages are with respect to GND. During transitions, this level may undershoot to -2.0V for periods of <20 ns.
2. Do not violate processor or chipset limitations on the INIT pin.
1. The device is designed to operate at temperatures beyond the normal commercial temperature range of 0° C to +70° C.
1. All currents are in RMS unless otherwise noted. These currents are valid for all packages.

Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional oper-
ation of the device at these or any other conditions
beyond those indicated in the operational sections of
this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect device reliability.
