1. All voltages are measured with respect to GND, unless otherwise specified. Typical voltages are TA = 25°C and represent a parametric norm.

Logic inputs accept input high voltages up to VMAX, even when the device is operating down to VMIN. Timing specifications are tested at logic

levels of VIL = 0.8 V for a falling edge, and VIH = 2.0 V for a rising edge.

2. SMBus timing specifications are guaranteed by design and are not production tested.
