PI3USB223ZMEX Diodes Incorporated

A product Line of Pb Diodes Incorporated Lead-free Green PI3USB223 USB 2.0 High-Speed and Audio Switches with Negative Signal Capability Features Description Single +2.7V to +4.4V Supply Voltage e PTh I3USB223 combines AC coupled audio signals and USB2.0 Low 50A Supply Current HS (480Mbps) on the same pins. This enables users to use a single -3dB Bandwidth: 1500MHz (typ) connector to drive either a USB end point or an audio end point. Low 2.5(typ)On-Resistance PI3USB223 incorporates gate pump technology required to maintain THD+N: 0.02% low Ron for ideal audio THD while reducing the capacitance aeff ct Shorting D+/R and D-/L to Vbus will not cause leakage when of high speed USB signals. The device also incorporates a substrate V = 0 DD pump technology which allows -2V signals to pass through the Internal Shunt Resistors for Click-and-Pop Reduction switch without causing any leakage. VBUS Detection for Automatic Switch Path Selection e PTh I3USB223 features protection on D+/R and D-/L to ensure no Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) damage will happen to the IC if these pins are shorted accidentally Halogen and Antimony Free. Green Device (Note 3) to Vbus as well as ensuring there is no leakage when V is on or DD Packaging (Pb-free & Green available): o. Aff lso, it includes VBUS detection (VB) to automatically switch 10-pin contact UQFN, 1.4 x 1.8, (ZM10) to the USB signal path upon detection of a valid VBUS signal. It also features internal shunt resistors on the audio path to reduce clicks and pops heard during output. The device is available in a space-saving 10-pin, 1.4mm x 1.8mm UQFN package, and operate over the -40C to +85C temperature range.
