Detailed Description
The MAX4906EF are ESD-protected analog switches
where the COM_ inputs are further protected up to
±15kV ESD without latchup or damage. The device is
targeted for USB 2.0 high-speed (480Mbps) switching
applications. The device still meets USB low- and full-
speed requirements and is suitable for 10/100 Ethernet
switching. The MAX4906EF features two SPDT switches.
The MAX4906EF is fully specified to operate from a single
+2.7V to +3.6V supply and is +5.5V fault protected.
When operating from a +2.7V to +3.6V supply, the low
threshold of the device permits them to be used with
logic levels as low as 1.4V. The MAX4906EF is based on
a charge-pump-assisted n-channel architecture and thus
operate at 170A (max) quiescent current. The device
features a standby mode to reduce the quiescent current
to less than 3A (max).
Digital Control Input
The MAX4906EF provides a single-digit control logic
input, IN. IN controls the position of the switches as
shown in the
