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

MAX3207
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
monitors (DVI, HDMI); PC peripherals (FireWire, USB 2.0); server interconnect (PCI Express,
Infiniband); datacom; and interchassis interconnect.

MAX1558H
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
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.
