The maximum cable length supported by the SN65C3238DBR is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length for a baud rate of 9600 is around 1000 feet (305 meters), while for a baud rate of 115200, it is around 100 feet (30.5 meters). However, it's recommended to consult the TI application note 'TIAA263' for more detailed information on cable length and baud rate limitations.
The SN65C3238DBR can be configured for half-duplex or full-duplex operation by connecting the RTS (Request to Send) and CTS (Clear to Send) pins. For half-duplex operation, connect RTS to CTS, and for full-duplex operation, leave RTS and CTS unconnected or connect them to separate control signals.
The power consumption of the SN65C3238DBR depends on the operating mode and the supply voltage. In normal operation, the typical supply current is around 10mA at 3.3V and 15mA at 5V. In shutdown mode, the typical supply current is around 1uA. Consult the datasheet for more detailed information on power consumption.
Yes, the SN65C3238DBR is compatible with 5V microcontrollers. The device has 5V-tolerant inputs, which allow it to interface with 5V logic levels. However, ensure that the VCC supply voltage is within the recommended range of 3.3V to 5.5V.
The SN65C3238DBR has built-in ESD protection on the RS-232 inputs, which can withstand electrostatic discharges up to ±15kV. However, it's still recommended to follow proper ESD handling procedures when handling the device, such as using an ESD wrist strap or mat, and storing the device in an ESD-protected package.
