SPECIFICATIONS  
TA = TMIN to TMAX, VCC = VMIN to VMAX, unless otherwise noted.  
All voltages are measured with respect to GND, unless otherwise specified. Typicals are at TA = 25°C and represent the most likely  
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. SMBus timing specifications  
are guaranteed by design and are not production tested.
