The SN65C3232DBR can support data rates up to 100 Mbps.
Yes, the SN65C3232DBR can be used in a multi-point configuration, but it requires an external repeater or hub to connect multiple devices.
The SN65C3232DBR has a common-mode voltage range of -7V to 12V, and it can handle common-mode voltages up to 12V without damage.
The maximum cable length that can be used with the SN65C3232DBR depends on the data rate and cable characteristics, but a general guideline is to limit the cable length to 100 meters or less.
No, the SN65C3232DBR does not have built-in termination resistors. External termination resistors are required to match the impedance of the transmission line.
