High-/Full-Speed USB 2.0 Switches  
with High ESD  
MAX4906EF  
General Description  
Features  
The MAX4906EF are electrostatic discharge (ESD)-pro-  
tected analog switches that combine low on-capacitance  
♦
15kV (Human Body Model) ESD Protection,  
on COM_  
(C ) and low on-resistance (R ) necessary for high-  
ON  
ON  
♦ Fully Specified for a Single +2.7V to +3.6V  
Power-Supply Voltage  
♦ Low 4Ω (typ), 7Ω (max) On-Resistance (R  
♦ -3dB Bandwidth: 500MHz (typ)  
♦ Low Bit-to-Bit Skew ≤ 20ps  
♦ Charge-Pump Noise = 90µV (typ)  
performance switching applications. The COM_ inputs  
are protected against ±±15k ESD without latchup or dam-  
age. The device is designed for USB 2.0 high-speed  
applications at 480Mbps. The switches also handle all the  
requirements for USB low- and full-speed signaling.  
)
ON  
The MAX4906EF features two single-pole/double-throw  
(SPDT) switches. The device is fully specified to operate  
from a single +2.7k to +3.6k power supply and is protect-  
ed against a +1.1k short to all analog inputs (COM_, NC_,  
NO_). This feature ma5es the MAX4906EF fully compliant  
with the USB 2.0 specification of +1.1k fault protection.  
The device features a low threshold voltage and a +±.4k  
♦ Charge-Pump Enable  
♦ No Need for Logic-Level Shifters for 1.4V or  
Above  
♦ COM Analog Inputs Fault-Protected Against  
_
Shorts to USB Supply Rail Up to +5.5V  
k , permitting them to be used with low-voltage logic.  
IH  
The device features a QP input that when driven high,  
turns the charge pump off and sets the device in standby  
mode. When the device is in standby mode, the quies-  
cent supply current is reduced to 3µA (max) and the  
switches remain operable.  
♦ Low Supply Current 3µA (max) in Standby  
♦ Space-Saving 10-Pin, 2mm x 2mm µDFN Package  
Ordering Information  
The MAX4906EF is available in a space-saving, 2mm x  
2mm µDFN pac5age and operates over a -40°C to +81°C  
temperature range.
