SPECIFICATIONS

ELECTRICAL CHARACTERISTICS

DC Specifications

All voltages are relative to their respective ground. All minimum/maximum specifications apply over the entire recommended operating

range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = 5 V, and VDD2 = 5 V, unless otherwise noted.

1 VIL < 0.5 V, VIH > 0.7 V.

2 ΔVS1L = VS1OL – VS1IL. This is the minimum difference between the output logic low level and the input logic low threshold within a given component. This ensures that

there is no possibility of the part latching up the bus to which it is connected.
