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.
