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
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
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
