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

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.

19-4597; Rev 0; 4/09

Note: All devices are specified over the -40°C to +85°C operating temperature range.

+ Denotes a lead(Pb)-free/RoHS-compliant package.
