MAX14508E–MAX14511E/  
MAX14509AE  
USB 2.0 Hi-Speed and Audio Switches  
with Negative Signal Capability  
General Description  
Benefits and Features  
Single +2.7V to +5.0V Supply Voltage  
● Low 12μA Supply Current  
The MAX14508E–MAX14511E/MAX14509AE high-ESD-  
protected DPDT switches multiplex Hi-Speed (480Mbps)  
USB and analog signals such as AC-coupled audio or  
video. These devices combine the low on-capacitance  
-3dB Bandwidth: 950MHz (typ)  
● Low 2.4Ω (typ) On-Resistance  
(C ) and low on-resistance (R ) necessary for high-  
ON  
ON  
performance switching applications in portable electronics,  
and include an internal negative supply to pass audio  
● Low 20mΩ (typ) R  
Flatness  
ON  
THD+N: 0.05%  
signals that swing below ground (down to V  
- 5.0V).  
CC  
COM Analog Inputs Fault Protected Against Shorts  
to +5.5V (MAX14508E/MAX14509E/MAX14510E/  
MAX14511E)  
The MAX14508E–MAX14511E/MAX14509AE also handle  
USB low-/full-speed signaling and operate from a +2.7V  
to +5.0V supply.  
Internal Shunt Resistors for Click-and-Pop Reduction  
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.
