ISL54228

The ISL54228 is a single supply, dual SPST (Single Pole/Single Throw) switch that is configured as a DPST. The features of ISL54228 are as follows: (1)High-Speed (480Mbps) and Full-Speed (12Mbps) Signaling Capability per USB 2.0; (2)1.8V Logic Compatible (2.7V to +3.6V supply); (3)OE/ALM Pin to Open all Switches and Indicate Overvoltage Fault Condition; (4)Power OFF Protection.

The following is about the absolute maximum ratings of ISL54228: (1)VDD to GND: -0.3 to 6.5V; (2)VDD to COMx: 10.5V; (3)COMx to Dx: 8.6V; (4)Input Voltages D+, D-: -0.3V to 6.5V, COM+, COM-: -5V to 6.5V, OE, LP: -0.3 to 6.5V; (5)Continuous Current (COM-/D-, COM+/D+): ±40mA.

The electrical characteristics of the ISL54228 are: (1)ON-Resistance, rON (High-Speed): 3.5 at VDD = 2.7V, OE/ALM = 1.4V, IDx = 17mA, VCOM+ or VCOM- = 0V to 400mV; (2)rON Matching Between Channels, rON (High-Speed): 0.2 at VDD = 2.7V, OE/ALM = 1.4V, IDx = 17mA, VCOM+ or VCOM- = Voltage at max rON; (3)rON Flatness, RFLAT(ON) (High-Speed): 0.26 at VDD = 2.7V, OE/ALM = 1.4V, IDx = 17mA, VCOM+ or VCOM- = 0V to 400mV.
