The PI3USB221AZUAEX is an integrated device designed to bridge USB communications devices with systems that include digital and analog voltage sources. As a part of an interface: analog switches: special purpose product range, this device offers a high-speed, low-cost solution for interfacing USB-based products directly to digital or analog systems. The PI3USB221AZUAEX’s unique features enable designers to safely connect USB to a variety of analog and digital systems, while also providing quality assurance against voltage overshoots and shorts. This makes the PI3USB221AZUAEX a stand out solution for any application that requires seamless communication between USB and voltages sources.

PI3USB221AZUAEX is a single-channel bi-directional USB2.0/3.0 switchable USB transceiver/hub chip that supports USB2.0 High Speed (480 Mbps), Full Speed (12 Mbps) and Low Speed (1.5 Mbps) communications and USB3.0 SuperSpeed (5 Mbps) communications. It integrates a non-blocking four-port USB hub with a programmable analog switch that operates in both SPST (On–Off) and SPDT (On–Off–On) modes. This makes it ideal for any application where switching between multiple digital or analog devices is needed. The PI3USB221AZUAEX supports four USB ports, one of which is designated as the “master” port, from which all other USB devices can be controlled. The other three ports can be used for downstream or upstream connections with USB peripherals.

PI3USB221AZUAEX supports four data channels, each of which can be individually configured to support USB2.0/3.0 data transfer rates. This speeds up data transfer speeds, which is especially helpful in applications that require high-speed data transfer. It also supports a range of analog switching functions, such as variable voltage switching, analog switching of multiple voltage sources, and voltage boost for single digital/analog devices. The PI3USB221AZUAEX also provides an adjustable analog amplitude threshold that helps identify voltage levels within certain limits. An adjustable halt pin feature also helps regulate power by automatically disabling devices when they enter a low-power state.

The PI3USB221AZUAEX is easy to configure and can be used with an external resistor and /or capacitor to control its interface speed. Its low voltage operation makes it ideal for applications where an isolated power supply is needed. This device is ideal for use in digital/analog interfacing applications, such as USB powered devices, automotive systems, memory card readers, gaming peripherals, and other consumer and industrial applications. With its high-performance features and low-cost solution, the PI3USB221AZUAEX is one of the most efficient and reliable USB to digital or analog bridging solutions available.
