LTC2864IS-2#TRPBF is a dual transceiver IC from Linear Technology described as a galvanically isolated RS-485/RS-422 transceiver. This latest multi-channel transceiver combines both industry standards, RS-485 and RS-422, in one 8-pin package, providing integrated protection against ±25 kV ESD, short-circuit fault protection, and EMI noise immunity. The device also is compact, easy-to-use, and cost-effective, making it suitable for a wide range of applications in the industrial, automotive, and communication markets.

In the industrial field, the LTC2864IS-2#TRPBF is well suited for applications such as industrial control, data acquisition, machine automation, and process control. It can also be used in motor control systems and can help provide protection against shorts, ESD/EMI, overvoltage, as well as providing typical isolation levels of up to 1 kVrms. In the automotive market, the LTC2864IS-2#TRPBF can be used to provide reliable and isolated communications in infotainment systems, traffic controllers, and parking systems. The device is also ideal for automotive ECU applications that require high-speed, galvanic isolation and fault protection. In communication markets, the device’s low-power, fault-protected and galvanically-isolated design makes it an ideal choice for communication systems, such as DSL modems, VoIP systems, and instrumentation systems.

The LTC2864IS-2#TRPBF is a two-channel, galvanically isolated transceiver. Each of the dual transceivers contains an isolated driver and receiver, an isolated power supply for each side, and an isolated converter. The device is capable of transmitting signals up to 50 Mbps over a wide range of temperatures and line conditions. The design of the LTC2864 also allows for a wide common-mode voltage range and supports full-duplex communication. The device is powered by a logic supply voltage of either 3V to 5.5V or 5V to 12V. The supply voltage of the driver is generated internally and regulated at 6V. The receiver can accept a logic level of either VCC or VIO depending on the voltage range of the logic. The driver has an enable pin that can be used to enable or disable the driver.

The LTC2864IS-2#TRPBF uses a process that prevents line faults from affecting the operation of the device. It does this by comparing an internal reference voltage with the actual line voltage. If the line voltage exceeds the reference voltage, the driver will be automatically disabled, preventing any damage to the device. The device also includes EMI filters to prevent EMI noise from affecting the signal. This helps ensure a more reliable data transmission over long distances.

Overall, the LTC2864IS-2#TRPBF is a cost-effective, robust, and easy-to-use solution that is well suited for a wide range of applications in both industrial and automotive markets. Its wide temperature range and wide common-mode voltage range support industrial and automotive operation, while its low-power consumption and fault protection ensure a reliable performance over long distances and in harsh environments.
