The MAX14531E–MAX14534E high ESD-protected DP3T switches multiplex Hi-Speed (480Mbps) 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 on-capacitance (C_ON) and low on-resistance (R_ON) 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 space-saving, 12-bump, 1.5mm x 2.0mm WLP package and operate over the -40°C to +85°C temperature range.
