DATASHEET
ISL54214
USB 2.0 High-Speed x 2 Channels/Stereo Audio Dual SP3T
(Dual 3 to 1 Multiplexer)
The Intersil ISL54214 is a single supply dual SP3T
analog switch that operates from a single supply in
the range of 2.7V to 4.6V. It was designed to
multiplex between audio stereo signals and two
different USB 2.0 high speed differential data signals.
The audio channels allow signal swings below ground,
allowing the multiplexing of the voice and data signals
through a common headphone connector in Personal
Media Players and other portable battery powered
devices.
The audio switch cells can pass ±1V ground
referenced audio signals with very low distortion
(<0.03% THD+N when driving 5mW into 32Ω loads).
The USB switch cells have very low ON capacitance
(8pF) and high bandwidth to pass USB high speed
signals (480Mbps) with minimal edge and phase
distortion.
The ISL54214 is available in a tiny 12 Ld
2.2mmx1.4mm ultra-thin QFN and 12 Ld 3mmx3mm
TQFN packages. It operates over a temperature range
of -40 to +85°C.
