Interface-drivers, receivers, transceivers are important components used in various applications to transmit or receive the signal. ISL32175EIBZ-T is a high speed performance RS-485 transceiver with enhanced ESD protection and robust EMI immunity for control of 2-wire and 4-wire data buses. This transceiver uses a fast power-saving Schmitt trigger input buffer and features a failsafe state when the input signal is terminated or floating. This device is ideal for long distance data communication and robotic applications.

ISL32175EIBZ-T Application Field

ISL32175EIBZ-T is a high performance RS-485 transceiver with low power consumption and excellent signal quality, EMC protection, and EMI immunity. It uses a patented on-chip driver with controlled slew rate and differential outputs to minimize EMI (electromagnetic interference) as well as reduce system power consumption. This device is especially well-suited for applications that require long distances such as distributed control systems and robotic networks. It is also used in power line communication applications, meters, home automation networks, industrial networks, and other similar applications. The device is RoHS qualified and is available in SOIC and TSSOP packages.

ISL32175EIBZ-T Working Principle

The ISL32175EIBZ-T is a Dual In-Line Package (DIP) High Speed RS-485 transceiver with a true fail-safe circuit. The fail-safe circuitry ensures that when the input signal is open or floating, the output signal remains in a low state. This transceiver features a high-impedance receiver input and a low-impedance Driver Output for long-distance communication. The receiver input translates input signals into digital data that is then retransmitted on the differential output, which is suitable for operation up to 1 Mbps (2.5 Mbps when power optimized mode is used). The two-wire bus of the ISL32175EIBZ-T can communicate with up to 32 devices on a bus.

The ISL32175EIBZ-T also incorporates an on-chip differential transmitter driver with slew rate control and a high common-mode rejection ratio that minimizes EMI and minimizes power consumption, making it ideal for applications with high data rates and long distances. In addition to its robust features, the device also features high ESD protection (HBM 7kV, CDM 8kV) for high-speed data lines.

In order to maximize system performance, the device can be programmed for the optimal output slew rate. The output slew rate can be adjusted between two selectable values, +/- 25 mV/µs or +/- 125 mV/ µs. The receiver input is active low (input voltage must be less than 0.8V) and the output drivers can be operated in low-power 3-state mode, making the device ideal for energy-efficient applications.

Overall, the ISL32175EIBZ-T is a high performance RS-485 transceiver that is designed for long-distance data communication and robotic networks. The device features fast power-saving Schmitt trigger input buffers, extended ESD and EMI protection, and robust fail-safe state when the input signal is terminated or floating. It is available in various packages and is ideal for power line communication applications.
