SPECIFICATIONS
ELECTRICAL CHARACTERISTICS
DC Specifications1
All minimum/maximum specifications apply over the entire recommended operating range, unless otherwise noted. All typical
specifications are at TA = 25°C, VDD1 = 3.3 V or 5 V, and VDD2 = 3.3 V or 5 V, unless otherwise noted.

1 All voltages are relative to their respective ground.
2 VIL < 0.5 V, VIH > 0.7 V.
3 ΔVS1 = VS1OL − VS1T. This is the minimum difference between the output logic low level and the input logic threshold within a given component. This ensures that there
is no possibility of the part latching up the bus to which it is connected.
