ADT7468
SPECIFICATIONS
T A = T MIN to T MAX , V CC = V MIN to V MAX , unless otherwise noted.
All voltages are measured with respect to GND, unless otherwise specified. Typicals are at T A = 25°C and represent most likely parametric
norms. Logic inputs accept input high voltages up to V MAX even when device is operating down to V MIN . Timing specifications are tested at
logic levels of V IL = 0.8 V for a falling edge and V IH = 2.0 V for a rising edge. SMBus timing specifications are guaranteed by design and are
not production tested.
