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 QP input 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 3A (max) and the
switches remain operable.
The MAX4906EF is available in a space-saving, 2mm x
2mm DFN package and operates over a -40°C to +85°C
temperature range.
