USB 2.0 High-Speed x 2 Channels/Stereo Audio

Dual SP3T (Dual 3 to 1 Multiplexer)

ISL54214

Features

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

Signaling Capability per USB 2.0

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.

• Low Distortion Negative Signal Capability Audio

Switches

• Power OFF Protection

• COM Pins Overvoltage Tolerant to 5.5V

• Low Distortion Headphone Audio Signals

- THD+N at 5mW into 32Ω Load . . . . . . . . <0.03%

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.

• Cross-talk (100kHz) . . . . . . . . . . . . . . . . . . -98dB

• OFF-Isolation (100kHz). . . . . . . . . . . . . . . 95.5dB

• Single Supply Operation (V ) . . . . . . 2.7V to 4.6V

• -3dB Bandwidth USB Switches. . . . . . . . . . . 700MHz

• 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)
