Frequently Asked Questions

Question: Is this IC suitable for 5V systems?

Answer: No, the SN65HVD10D operates exclusively at 3.3V (3V–3.6V range). Use voltage translators for 5V compatibility.

Question: What does “half-duplex” mean for this transceiver?

Answer: Half-duplex permits data transmission in only one direction at a time, requiring protocol-controlled direction switching.

Question: Can I use this in outdoor installations?

Answer: Yes, its -40°C to 85°C temperature range and noise immunity make it suitable for outdoor industrial applications.

Question: How does receiver hysteresis improve performance?

Answer: The 35mV hysteresis creates a noise rejection zone, preventing signal oscillation near threshold voltages.

Question: Is this component RoHS compliant?

Answer: Yes, all TI components supplied by PCX meet current RoHS 3 directives.

Question: Why choose obsolete parts for new designs?

Answer: Many industrial systems require component consistency for long-term maintenance. PCX maintains inventory of certified obsolete ICs for lifecycle support.
