Overview

Description

PI3USB221AZUAEX is a 2:1 USB 2.0 high-speed data switch from the PI3USB221 family (Pericom/Renesas). It muxes the D+ and D- data lines of a USB link between two downstream ports (or between a host and a device) under control of a select input, with an optional enable control to disconnect the path.
Key points:
- 2:1 USB 2.0 high-speed data switch (up to 480 Mbps; supports FS/HS signaling).
- D+ and D− lines routed through low on-resistance paths for good signal integrity.
- Control: select input (and enable) to switch which port is connected.
- Suitable for USB OTG, portable hubs, docking/attachment switches, or any application needing to route a single USB link to one of two devices.
Package/variant notes:
- AZUAEX suffix indicates a specific package and temperature/lead-frame variant; check the datasheet for exact package, supply, and operating conditions.
For design, review the datasheet for pinout, timing, electrical specs, ESD protection, and layout guidelines.

Features

PI3USB221AZUAEX is a USB 2.0 high‑speed 2:1 data switch. Key features:
- 2-channel USB 2.0 high‑speed switch (D+ and D−) with 480 Mbps signaling
- 2:1 mux: routes one of two upstream USB devices to a single USB port using a single select control
- Bidirectional data path with 3‑state outputs when disabled
- Built‑in ESD protection on D+/D− lines
- Low on‑resistance and fast switching to preserve USB signal integrity
- Single‑supply operation; RoHS‑compliant packaging
- Small 8‑pin package suitable for compact designs
Note: For exact electrical specs (voltage range, RON,‑temp range), please consult the official datasheet.

Package

8-pin package (SOP-8 / US8 family; i.e., an 8-pin small-outline package).

Pinout

- Pin count: 8 pins (8-pin package).
- Function: USB 2.0 high-speed 2:1 data switch (multiplexer) that routes the D+ / D− differential pair between a single upstream port and one of two downstream ports, with enable/select control.

Manufacturer

- Manufacturer: Diodes Incorporated (the PI3USB221 series originated with Pericom Semiconductor, which Diodes acquired in 2015).
- What kind of company: A semiconductor company that designs and manufactures high-speed connectivity ICs, such as USB/PCIe/HDMI switches and crosspoint switches.

Application

PI3USB221AZUAEX is a 2:1 USB 2.0 high-speed data switch. Applications:
- OTG host/device path switching in mobile devices
- USB docking stations and front-panel port multiplexing
- Set‑top boxes, TVs and AV gear routing a single USB controller to two devices/hosts
- Automotive infotainment USB path switching
- General USB 2.0 path selection in hubs, switches and multiplexers

Equivalent

Direct equivalent: Texas Instruments TS3USB221 (USB 2.0 2:1 crosspoint switch). Other direct cross-references depend on package; check distributor cross-reference (Mouser/Digi-Key) for Renesas/Pericom PI3USB221 variants or similar 2:1 USB mux switches from TI, On Semiconductor, etc.
