MAX14508E–MAX14511E/
MAX14509AE
USB 2.0 Hi-Speed and Audio Switches
with Negative Signal Capability
General Description
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
(CON) and low on-resistance (RON) necessary for high-
performance switching applications in portable electronics,
and include an internal negative supply to pass audio
signals that swing below ground (down to VCC - 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.
