Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. Continuous short−circuit operation to ground at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of 45 mA over long term may adversely affect reliability. Shorting output to either V+ or V− will adversely affect reliability.

Active power represents normal data communication. Standby power is when the device is enabled for operation but there is no LAN traffic (cable not connected). Power down current is the minimum power state used when not connected and mobile. 3. Measured by the voltage drop between A and B pins at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (A & B) pins. 4. Guaranteed by design and/or characterization. 5. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25 ns for 10 pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side. http://onsemi.com 4 NCN7200 GIGABIT ETHERNET LAN SWITCH WITH 2:1 MUX/ DEMUX AND POWER DOWN FEATURE (Min / Max values are at VDD = 3.3 V ±10%, TA = −40°C to +85°C.

For example, given a +3.3 V supply, the output enables or select pins may be driven low to 0 V and high to 3.6 V: driving the control pins to the rails minimizes power consumption. Proper power−supply sequencing is advised for all CMOS devices. It is recommended to always apply VDD before applying signals to the input/output or control pins.
