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 electron-

ics, 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 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.
