SN65HVD34 3V 全双工 RS-485 驱动器和接收器
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 are fully enabled with no external enabling pins.
The SN65HVD33, SN65HVD34, and SN65HVD35 have active-high driver enables and active-low receiver enables. A low, less than 1µA, 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
