The MAX3086ECSD+T is a high-performance, low-power RS-485/RS-422 transceiver, which provides a low-pin-count interface for two-channel point-to-point, half duplex applications. This transceiver operates from a 1V to 5.5V single supply making it suitable for applications with a wide range of operating voltages. Additionally, the MAX3086ECSD+T features 25kΩ differential impedance as well as common-mode range spanning -7V to 12V. This makes it a great choice for long-distance applications due to its higher signal integrity.

The MAX3086ECSD+T consists of two low-voltage differential transceivers and a protected, high-side, single-supply current limiting receiver driver. Each transceiver contains six outputs which include a 5V or 3V TTL/CMOS compatible logic compatible driver, a 3-state driver, and a protected-receiver input. Other features include a low power sleep mode, a wide common-mode range, and a low-current shutdown mode. The maximum data rate operation is 10Mbps and the maximum pulse skew is 100ns. The input and output protection of the MAX3086ECSD+T is 750V and 400V, respectively.

The MAX3086ECSD+T is suitable for applications requiring a low-cost, low-power, high-speed, low-skew, and low-EMI solution. Typical applications include automotive, industrial, and communications equipment, such as RS-485/RS-422 networks and long-distance data links. The MAX3086ECSD+T is also suitable for other applications such as wireless data links, point-to-point links, and computer systems.

The working principle of the MAX3086ECSD+T is based on the differential signaling technique which uses two wires or traces instead of the traditional single-ended signaling which only uses one wire. The differential signaling technique has several advantages, such as improved noise immunity and longer distance transmission. In the case of the MAX3086ECSD+T, the two wires are driven by the transmitter outputs and the receiver input. The drivers are configured to drive complementary voltages on the two wires. The receiver on the other side reads the input and interprets the combined signals from the two wires. If the signals on the two wires differ, it indicates that there is noise present on one of them, but since the receiver is reading the combined signals, the noise can be filtered out.

The other main feature of the MAX3086ECSD+T is its high-side current limiting receiver driver which as the name implies limits the current of the receiver and thus ensuring a high data rate and low EMI. The drivers are also equipped with over-voltage protection and short-circuit protection which help against incorrect wiring, transient overvoltages, and current surges. The drivers also have a robust ESD protection which helps against electrostatic discharge.

The MAX3086ECSD+T is a great solution for applications that require a low-cost, low-power, differential transceiver. Its high data rate and low EMI make it suitable for long-distance applications as well as for applications that require robust ESD protection. Additionally, its wide common-mode range and low-current shutdown mode make it ideal for use in applications that have a wide operating voltage range. The MAX3086ECSD+T is an ideal solution for RS-485/RS-422 networks and long-distance data links.
