SN65HVD34中文资料带使能信号的 3V 全双工 RS-485 驱动器和接收器数据手册TI规格书

描述 Description

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.
