MAXIM MAX14531E, MAX14534E Technical data

General Description

The MAX14531E–MAX14534E high ESD-protected
DP3T switches multiplex Hi-Speed (480 Mbps) USB
signals, low/full-speed USB signals, and analog sig­nals such as AC-coupled audio or video through any
of three channels. These devices combine the low on­capacitance (C

ON

) and low on-resistance (RON) nec­essary 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 func­tion 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 resis­tors on audio channels to reduce clicks and pops
heard at the output.

The MAX14531E–MAX14534E are available in a space­saving, 12-bump, 1.5mm x 2.0mm WLP package and
operate over the -40°C to +85°C temperature range.

ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VCC= +2.7V to +5.5V, TA= -40°C to +85°C, unless otherwise noted. Typical values are at VCC= +3.0V, TA= +25°C, unless other­wise noted.) (Note 2)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-

layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial
