USB Section Components

Part Number	Functional Description
	The MAX4906F analog multiplexer combines the low on-capacitance (CON) and low on-
	resistance (RON) necessary for high-performance switching applications. This device is
MAX4906F	designed for USB 2.0 Hi-Speed applications at 480Mbps. The MAX4906F also handles all
	the requirements for USB low- and full-speed signaling.

	The MAX4899AE analog multiplexer combines the low on-capacitance (CON) and low on-
	resistance (RON) necessary for high-performance switching applications. This device is
MAX4899AE	designed for USB 2.0 Hi-Speed applications at 480Mbps. The MAX4899AE also handles all
	the requirements for USB low- and full-speed signaling.

	The MAX3207E is a low-capacitance, ±15kV ESD-protection diode array with an integrated
	TVS clamp. The device is suitable for high-speed and general-signal ESD protection. Low
	input capacitance makes this device ideal for ESD protection of signals in HDTV; PC
MAX3207	monitors (DVI, HDMI); PC peripherals (FireWire, USB 2.0); server interconnect (PCI Express,
	Infiniband); datacom; and interchassis interconnect.

	The MAX1558H is a dual, current-limited switch with autoreset that latches the switch off if it
	is shorted for more than 20ms, thus saving system power. The shorted output is then tested
	to determine when the short is removed so the channel can restart automatically. Each
MAX1558H	channel delivers up to 1.2A and meets all IEC specifications for USB ports. The MAX1558H
	safety features ensure that the USB port is protected.
