MAX4906EFELB+T
High-/Full-Speed USB 2.0 Switches with High ESD
General Description
The MAX4906EF are electrostatic discharge (ESD)-pro-
tected analog switches that combine low on-capacitance
(CON) and low on-resistance (RON) necessary for high-
performance switching applications. The COM_ inputs
are protected against ±15kV 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.
The MAX4906EF features two single-pole/double-throw
(SPDT) switches. The device is fully specified to operate
from a single +2.7V to +3.6V power supply and is protect-
ed against a +5.5V short to all analog inputs (COM_, NC_,
NO_). This feature makes the MAX4906EF fully compliant
with the USB 2.0 specification of +5.5V fault protection.
The device features a low threshold voltage and a +1.4V
VIH, permitting them to be used with low-voltage logic.
The device features a QPinput 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.
The MAX4906EF is available in a space-saving, 2mm x
2mm µDFN package and operates over a -40°C to +85°C
temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2:All units are 100% production tested at TA= +25°C. Limits over the operating temperature range are guaranteed by design
and not production tested.
Note 3:The switch will turn off for voltages above (VFP); therefore, protecting downstream circuits in case of a fault condition.
Note 4:Fault-protection trip threshold limits are not production tested; guaranteed by design.
Note 5:ΔRON(MAX)= | RON(CH1) – RON(CH2) |
Note 6:Flatness is defined as the difference between the maximum and minimum value of on-resistance, as measured over
specified analog signal ranges.
Note 7:Between any two switches.
Note 8:Noise specification is measured peak to peak.
Note 9:Switch off-capacitance, switch on-capacitance, output skew between switches, and output skew same-switch limits are not
production tested; design guaranteed by correlation.
