SN65HVD179 3.3V 全双工 RS 485 驱动器和接收器
The SN65HVD179 is a differential line driver and differential-input line receiver that operates with a 5-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.
The differential bus driver and receiver 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 SN65HVD179 is fully enabled with no external enabling pins.
The 1/2 unit load receiver has a high receiver input resistance
