Texas Instruments provides a recommended PCB layout in the application note SLVAE04, which includes guidelines for component placement, routing, and grounding to minimize EMI and ensure reliable operation.
The DS14C335MSA requires proper termination to prevent signal reflections and ensure signal integrity. TI recommends using a 50-ohm termination resistor at the receiver end, and a 100-ohm differential termination resistor at the transmitter end, as shown in the datasheet.
The maximum cable length supported by the DS14C335MSA depends on the specific application and the type of cable used. As a general guideline, TI recommends keeping the cable length below 10 meters to ensure signal integrity. Longer cable lengths can be used, but may require additional signal conditioning or repeaters to maintain signal integrity.
TI provides a troubleshooting guide in the application note SLVAE03, which covers common issues with the DS14C335MSA, such as signal loss or data corruption, and provides steps to identify and resolve these issues.
The DS14C335MSA has a maximum operating temperature of 85°C. To ensure reliable operation in high-temperature environments, TI recommends using a heat sink or thermal pad to dissipate heat, and ensuring good airflow around the device. Additionally, the device should be operated within the recommended power supply voltage range to minimize thermal stress.
