USB 2.0 Hi-Speed and Audio Switches with
Negative Signal Capability and ±15kV ESD
General Description
The MAX14531E–MAX14534E high ESD-protected
DP3T switches multiplex Hi-Speed (480 Mbps) USB
signals, low/full-speed USB signals, and analog sig-
nals such as AC-coupled audio or video through any
of three channels. These devices combine the low on-
capacitance (C_ON) and low on-resistance (R_ON) nec-
essary for high-performance switching applications in
portable electronics, and include an internal negative
supply to pass AC-coupled audio signals that swing
below ground (down to -2.0V). The MAX14531E–
MAX14534E operate from a +2.7V to +5.5V supply.
The MAX14531E–MAX14534E have a shutdown func-
tion to reduce supply current and set all channels to
high impedance. The MAX14531E–MAX14534E feature
a VBUS detection function through the CB0 input to
automatically switch to the default USB signal path
upon detection of a valid VBUS signal. The
MAX14532E/MAX14534E feature internal shunt resis-
tors on audio channels to reduce clicks and pops
heard at the output.
The MAX14531E–MAX14534E are available in a space-
saving, 12-bump, 1.5mm x 2.0mm WLP package and
operate over the -40°C to +85°C temperature range.
