MAXIM MAX14508E, MAX14511E, MAX14509AE User Manual

General Description

The MAX14508E–MAX14511E/MAX14509AE high-ESD­protected DPDT switches multiplex Hi-Speed (480Mbps)
USB and analog signals such as AC-coupled audio or
video. These devices combine the low on-capacitance
(CON) and low on-resistance (RON) necessary for high­performance switching applications in portable electron­ics, and include an internal negative supply to pass
audio signals that swing below ground (down to V

CC

-

5.0V). The MAX14508E–MAX14511E/MAX14509AE also
handle USB low-/full-speed signaling and operate from
a +2.7V to +5.0V supply.

The MAX14508E–MAX14511E feature +5.5V fault pro­tection on COM1 and COM2, making these devices
compliant with the USB 2.0 fault-protection specification.
The MAX14510E/MAX14511E feature a VBUS detection
input (VB) to automatically switch to the USB signal path
upon detection of a valid VBUS signal. The MAX14508E/
MAX14510E feature internal shunt resistors on the audio
path to reduce clicks and pops heard at the output. The
MAX14508E/MAX14509E/MAX14509AE have an enable
input (EN) to reduce supply current and set all channels
to high impedance when driven low.

The MAX14508E–MAX14511E/MAX14509AE are avail­able in a space-saving, 10-pin, 1.4mm x 1.8mm UTQFN
package, and operate over the -40°C to +85°C temper­ature range.

(VCC= +2.7V to +5.0V, TA= -40°C to +85°C, unless otherwise noted. Typical values are at VCC= +3.0V, TA= +25°C.) (Note 3)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
