3 / 6 page  3 PS8698A 02/01/05 PI3USB40 3.3V, Wide Bandwidth, 8-Channel, 2:1, Mux/DeMux USB 2.0 Switch with Single Enable Notes: 1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading. 3. Per TTL driven input (control inputs only); A and B pins do not contribute to ICC. Dynamic Electrical Characteristics Over the Operating Range (TA=-40º to +85ºC, VCC=3.3V±10%, GND=0V) Parameter Description Test Conditions Min. Typ.(2) Max. Units XTALK Crosstalk RL = 100Ω, f = 250MHz -27 dB OIRR OFF Isolation -32 BW Bandwidth –3dB RL = 100Ω 500 MHz Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Guaranteed by design. 3. 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 0.25ns for 10pF 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. Power Supply Characteristics Parameters Description Test Conditions(1) Min. Typ.(2) Max. Units ICC Quiescent Power Supply Current VCC = Max., VIN = GND or VCC 800 µA Notes: 1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading. 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. This parameter is determined by device characterization but is not production tested. Capacitance (TA = 25°C, f = 1MHz) Parameters(5) Description Test Conditions Typ. Max.
