The SN65HVD3x devices are 3-state differential line drivers and differential-input line receivers that operate with 3.3-V power supply. Each driver and receiver has separate input and output pins for full-duplex bus communication designs. They are designed for RS-422 and RS-485 data transmission over cable lengths of up to 1500 meters. The SN65HVD30, SN65HVD31, and SN65HVD32 devices are fully enabled with no external enabling pins. The SN65HVD33, SN65HVD34, and SN65HVD35 devices have active-high driver enables and active-low receiver enables. A low, less than 1 µA, standby current can be achieved by disabling both the driver and receiver. All devices are characterized for ambient temperatures from –40°C to 85°C. Low power dissipation allows operation at temperatures up to 105°C or 125°C, depending on package option.

The SN65HVD37 combines a robust differential driver and a receiver with high noise immunity for demanding industrial applications. The driver differential outputs and the receiver differential inputs are separate pins, to form a bus port for full-duplex (four-wire) communications. The driver and receiver can be independently enabled, and feature a wide common-mode voltage range, making this device suitable for multi-point applications over long cable runs. The SN65HVD37 is characterized over the temperature range of –40ºC to 85 ºC.

The SN65HVD379 is a differential line driver and differential-input line receiver that operates with a 3.3-V power supply. Each driver and receiver has separate input and output pins for full-duplex bus communication designs. They are designed for balanced transmission lines and interoperation with ANSI TIA/EIA-485A, TIA/EIA-422-B, ITU-T v.11, and ISO 8482:1993 standard-compliant devices. These differential bus drivers and receivers are monolithic, integrated circuits designed for full-duplex bi-directional data communication on multipoint bus-transmission lines at signaling rates(1)up to 25 Mbps. The SN65HVD379 is fully enabled with no external enabling pins. The 1/2 unit load receiver has a higher receiver input resistance. This results in lower bus leakage currents over the common-mode voltage range, and reduces the total amount of current that an RS-485 driver is forced to source or sink when transmitting. The balanced differential receiver input threshold makes the SN65HVD379 more compatible with fieldbus requirements that define an external failsafe structure. (1)The signaling rate of a line is the number of voltage transitions that are made per second expressed in the units bps (bits per second).

The SN65HVD485E device is a half-duplex transceiver designed for RS-485 data bus networks. Powered by a 5-V supply, it is fully compliant with the TIA/EIA-485A standard. This device is suitable for data transmission up to 10 Mbps over long twisted-pair cables and is designed to operate with very low supply current, typically less than 2 mA, exclusive of the load. When the device is in the inactive shutdown mode, the supply current drops below 1 mA. The wide common-mode range and high ESD protection levels of this device make it suitable for demanding applications such as: electrical inverters, status/command signals across telecom racks, cabled chassis interconnects, and industrial automation networks where noise tolerance is essential. The SN65HVD485E device matches the industry-standard footprint of the SN75176 device. Power-on reset circuits keep the outputs in a high-impedance state until the supply voltage has stabilized. A thermal-shutdown function protects the device from damage due to system-fault conditions. The SN65HVD485E device is characterized for operation from –40°C to 85°C air temperature.
