The maximum cable length supported by the SN65HVD22D is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length is around 100 meters at 9600 bps and 10 meters at 1 Mbps.
To ensure reliable communication in noisy environments, it is recommended to use shielded cables, implement proper grounding and shielding, and use noise filtering techniques such as common-mode chokes or ferrite beads.
The SN65HVD22D supports data rates up to 1 Mbps.
Yes, the SN65HVD22D can be used in half-duplex mode by connecting the transmitter output to the receiver input through a directional control signal.
To handle bus contention in a multi-master system, it is recommended to implement a non-destructive bit-wise arbitration scheme, where each master device checks the bus state before transmitting data.
