The PI3USB102ZLEX is an advanced 3.3V-powered Analog Multiplexer/Demultiplexer integrated circuit (IC) from Diodes Incorporated designed for isolated data communications applications providing USB HID or Mass Storage connectivity. The device is specifically designed for low-voltage level signalling interfaces, allowing data transfer rates up to 2Mbps by connecting USB devices to industrial control systems and PLCs. It contains two separate channels for data transfer: one for sending data from the industrial controller to the USB device, and one for sending data from the USB device to the industrial controllers. In addition, the device is designed to support simultaneous bidirectional data transfers, allowing for high speed communication.

The PI3USB102ZLEX, classified as an analog switch of special purpose, is a low-capacitance, high-performance switch that is capable of operating at a maximum voltage of 5.5V and up to a 5.5Gbps data rate. Its high switching speed with low propagation delays allows for fast switching speeds between signals, eliminating false time delays and providing better system performance. Moreover, it features an adjustable impedance characteristic, which allows users to fine tune the edge rate of their signals.

The main advantages of the PI3USB102ZLEX are its low power consumption and high signal integrity. It provides a low current-consumption feature that minimizes heat generated, which enhances the reliability of the device and prevents against unwanted system shutdowns. Additionally, the device\'s low-noise characteristics and improved EMI/RFI emission reduce signal noise and reduce the need for costly external filtering, making it an ideal choice for applications requiring a high level of signal integrity.

The PI3USB102ZLEX, when utilized in its many application fields, works by switching between two signals. It is designed to offer multiplexing, or the ability to switch between two input or output signals. When used in USB communication applications, the device is capable of providing bidirectional data communication of up to five times higher than the industry standard. The device is engineered to ensure that the received USB signals are as original as the signals sent. This is accomplished by using automatic level-shifting features to detect the USB signal level and adjust the drive voltage accordingly.

The PI3USB102ZLEX also features robust ESD protection and is capable of withstanding up to ±15kV of ESD per IEC 61000-4-2 minimum. The device is also protected against EMI and other external interferences, ensuring that communication signals remain as original as possible. Furthermore, the device is designed to operate at low voltage levels and supports up to five different signal speed grades, allowing for greater flexibility when used in different applications.

In summary, the PI3USB102ZLEX is a versatile IC designed to provide improved signal integrity and faster signal switching in data communications applications. It is designed to support multiplexing between two signal sources, utilizing automatic voltage level shifting for improved robustness and signal integrity. The device is also protected against EMI and ESD, and can be configured to operate at low signal levels and multiple signal rates, making it an ideal choice for industrial data communication applications.
