USB 2.0 Hi-Speed and Audio Switches
with Negative Signal Capability
8–/MX14509AE
General Description
Features
♦ Single +2.7V to +5.0V Supply Voltage
♦ Low 12µA Supply Current
♦ -3dB Bandwidth: 950MHz (typ)
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
♦ Low 2.4Ω (typ) On-Resistance
(C ) and low on-resistance (R ) necessary for high-

♦ COM Analog Inputs Fault Protected Against Shorts
to +5.5V (MAX14508E/MAX14509E/MAX14510E/

5.0V). 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 (MAX14508E/MAX14510E)
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.
♦ VBUS Detection for Automatic Switch Path
Selection (MAX14510E/MAX14511E)
♦ Space-Saving Package: 10-Pin, 1.4mm x 1.8mm
