The maximum cable length supported by the SN65HVD21D 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.
The SN65HVD21D can be configured for half-duplex or full-duplex operation by connecting the RTS (Request to Send) pin to the CTS (Clear to Send) pin for half-duplex operation, or by connecting the RTS pin to a logic high and the CTS pin to a logic low for full-duplex operation.
The SN65HVD21D supports data rates up to 1 Mbps.
The SN65HVD21D has built-in error detection and correction mechanisms, including parity checking and framing error detection. Additionally, the device has a status register that can be used to monitor the device's operating status and detect errors.
Yes, the SN65HVD21D is designed to operate in harsh environments, including temperatures ranging from -40°C to 85°C, and can withstand electromagnetic interference (EMI) and radio-frequency interference (RFI).
