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

Features

• High Speed (480Mbps) and Full Speed (12Mbps)

Signaling Capability per USB 2.0

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.

• Low Distortion Negative Signal Capability Audio

Switches

• Power OFF Protection

• COM Pins Overvoltage Tolerant to 5.5V

• Low Distortion Headphone Audio Signals

- 0.03% THD+N at 5mW into 32ΩLoad

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.

• -98dB cross-talk (100kHz)

• 95.5dB OFF-Isolation (100kHz)

• 2.7V to 4.6V Single Supply Operation (V

)

• 700MHz of -3dB Bandwidth USB Switches

• Available in Tiny 12 Ld µTQFN and TQFN Packages

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.

• Compliant with USB 2.0 Short Circuit

Requirements Without Additional External

Components

• Pb-Free (RoHS Compliant)
