High-/Full-Speed USB 2.0 Switches
General Description
The MAX4906/MAX4906F/MAX4907/MAX4907F analog
switches combine the low on-capacitance (C
ON
) and
low on-resistance (R
ON
) necessary for high-perfor-
mance switching applications. These devices are
designed for USB 2.0 high-speed applications at
480Mbps. These switches will also handle all the
requirements for USB low- and full-speed signaling.
The MAX4906/MAX4906F feature two single-pole/dou-
ble-throw (SPDT) switches, and the MAX4907/
MAX4907F feature two single-pole/single-throw switches
(SPST). The MAX4907/MAX4907F have a low 7Ω (max)
on-resistance and 7pF (max) on-capacitance. These
devices are fully specified to operate from a single
+3.0V to +3.6V power supply and are protected against
a +5.5V short to COM1 and COM2. This feature makes
them fully compliant with the USB 2.0 specification of
+5.5V fault protection. These devices feature a low
threshold voltage and a +1.4V V
IH
, permitting them to
be used with low-voltage logic. The MAX4906/
MAX4906F/MAX4907/MAX4907F operate at 300µA
(max) quiescent current and feature a shutdown input
to reduce the quiescent current to less than 2µA (max).
The MAX4906/MAX4906F/MAX4907/MAX4907F are avail-
able in space-saving, 2mm x 2mm µDFN packages and
operate over a -40°C to +85°C temperature range.
