Description
General part information
SN65HVD379 Series
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.
