MAX4907F Maxim, MAX4907F Datasheet - Page 10

• Manufacturer Part Number: MAX4907F
• Description: The MAX4906/MAX4906F/MAX4907/MAX4907F analog switches combine the low on-capacitance (CON) and low on-resistance (RON) necessary for high-performance switching applications
• Manufacturer: Maxim

The MAX4906/MAX4906F/MAX4907/MAX4907F analog
switches are targeted for USB 2.0 high-speed
(480Mbps) switching applications. These devices still
meet USB low- and full-speed requirements and are
suitable for 10/100 Ethernet switching. The MAX4906/
MAX4906F feature two SPDT switches, while the
MAX4907/MAX4907F feature two SPST switches. The
MAX4907/MAX4907F switch configurations have a low
7Ω (max) on-resistance and 7pF (max) on-capacitance.

The MAX4906/MAX4906F/MAX4907/MAX4907F are fully
specified to operate from a single +3.0V to +3.6V supply
and are available with +5.5V fault protection (MAX4906F/
MAX4907F). When operating from a +3.0V to +3.6V sup-
ply, the low threshold of these devices permits them to
be used with logic levels as low as 1.4V.The
MAX4906/MAX4906F/MAX4907/MAX4907F are based
on a charge-pump-assisted n-channel architecture and
thus operate at 300µA (max) quiescent current. These
devices all feature a shutdown input to reduce the quies-
cent current to less than 2µA (max).
