The SN75110ADR is a quad differential line driver designed to meet the requirements of the TIA/EIA-485 Standard pertaining to balanced differential communication line drivers and receivers. This standard defines a driver with a slew rate of up to 30-V/µs and that it be capable of driving four unterminated lines with a rate of 80-mA of DC current. The SN75110ADR is an ideal choice for high-speed communication line drivers for half-duplex and full-duplex applications.

The SN75110ADR features an integrated 4-channel line driver with four differential line drivers, providing drive capability to four independent data lines(A, B, C, and D). The device contains four differential drivers, each having one output pin and one inverted output pin. The differential line drivers are designed so that they can drive four unterminated twisted pairs of wires, along with a separate common-mode ground line.

The SN75110ADR provides full galvanic isolation between the logic signal inputs and the line driver outputs. It achieves galvanic isolation using optical isolators, which provide a fully optically-isolated opto-coupler. This isolator provides signal level and ground isolation between the logic component and the line drivers, allowing the connection of different ground potentials.

The SN75110ADR features two input pins, one for data and one for common-mode ground. Data is input to the input pins via an optically-isolated differential latch circuit. The latch allows data to be transmitted and received over an unterminated transmission line, which can be up to 1,500 meters in length. The latch also provides support for half-duplex and full-duplex communication.

The SN75110ADR has two output pins that drive the transmitted signal out. The device is capable of driving four unterminated differential lines with a slew rate of up to 30-V/µs and a DC current of up to 80-mA. This allows the SN75110ADR to be used in a variety of applications, including high-speed half- and full-duplex communication links, motor control systems, and signal and power distribution systems.

The SN75110ADR also has the capability to bind to three additional devices in order to extend its signal transmission range. This feature is called Daisy Chaining and allows the SN75110ADR to act as the interface between multiple devices. The daisy chained devices are connected in a star-like configuration, with each device in the chain having its own separate power supply and common-mode ground.

The SN75110ADR is a high-performance transmission line driver that is ideal for unterminated and daisy-chained communication applications. It features differential line drivers that are capable of driving up to four unterminated lines with a rate of 80-mA of DC current, and it provides galvanic isolation between logic signals and the line driver outputs. The SN75110ADR also features the capability to daisy chain multiple devices in order to extend signal transmission range. All of these features make the SN75110ADR an ideal choice for high-speed communication line drivers in half-duplex and full-duplex applications.
