VTERM OPERATION ISL54400 ONLY When a USB cable from a computer is connected to a USB device a VrggM voltage must be applied to a speed indicating pull up resistor to properly terminate the bus and identify whether the USB device is a full speed or low speed device to facilitate proper digital transmission When the cable is removed from the device this VrERM voltage must be disconnected from the speed indicating pull up resistor The ISL54400 device can perform this operation When Vpp gt 2 5V and Vgus 2 Vpp 0 8V the VrggM pin pin 10 outputs an open circuit voltage equal to the voltage at the Vgus pin Otherwise the VTER pin will be in a HI Z state The ISL54400 VTggw circuitry has an internal series resistor approximately equal to 5 3kO For a full speed USB application it is recommended you use a 5 speed indicating pull up resistor When the USB bus is in the idle state a 5 resistor will put the D line voltage in the range of 2 7V to 3 6V as required by the USB specification For low speed USB application it is recommended you use 11 intersil FN6240 3 July 12 2006 ISL54400 ISL54401 ISL54402 a 2kO 5 pull up resistor at the D line in order to meet the USB connect and disconnect timing requirements ISL54402 Operation The ISL54402 is an audio data switch Its logic control is typical of a standard dual SPDT switch The digital control for the ISL54402 are the IN pins pin 2 and p
