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 most likely parametric  
norms. Logic inputs accept input high voltages up to VMAX even when 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.
