The MAX4906/MAX4906F/MAX4907/MAX4907F provide
a single-digit control logic input, IN. IN controls the
position of the switches as shown in the Functional
Diagram/Truth Table. Driving IN rail-to-rail minimizes
power consumption. With a +3.0V to +3.6V supply volt-
age range, these devices are +1.4V logic compatible.
The on-resistance of the MAX4906/MAX4906F/
MAX4907/MAX4907F is very low and stable as the ana-
log input signals are swept from ground to V+ (see the
Typical Operating Characteristics). These switches are
bidirectional, allowing NO_, NC_, and COM_ to be con-
figured as either inputs or outputs.
The MAX4906F and MAX4907F feature +5.5V fault pro-
tection to COM1 and COM2. Fault protection prevents
these switches from being damaged due to shorts to
the USB bus voltage rail.

The MAX4906/MAX4906F feature a shutdown mode
that reduces the quiescent current supply to less than
2µA. Drive SHDN/EN high to place the devices in high-
impedance mode. When SHDN/EN is driven low, the
devices are normal in operation.
The MAX4907/MAX4907F feature a SHDN input that
reduces the quiescent current supply to less than 2µA.
Drive SHDN high to place the devices in low current
mode. The devices can be used in low current mode, but
with a reduced analog voltage range of 0 < V
1.5V and reduced performance. When SHDN is driven
low, the MAX4907/MAX4907F are in normal operation.
The MAX4906/MAX4906F/MAX4907/MAX4907F analog
switches are fully compliant with the USB 2.0 specifica-
tion. The low on-resistance and low on-capacitance of
these switches make them ideal for high-performance
switching applications. The MAX4906/MAX4906F are
