MAX14508EEVB+

P1-P3P4-P6P7-P9P10-P12P13-P15
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
(C
ON
) and low on-resistance (R
ON
) necessary for high-
performance switching applications in portable electron-
ics, 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 pro-
tection 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 avail-
able in a space-saving, 10-pin, 1.4mm x 1.8mm UTQFN
package, and operate over the -40°C to +85°C temper-
ature range.
