Frequently Asked Questions
What is the maximum signaling rate supported by the SN65HVD33D?
The SN65HVD33D supports a maximum signaling rate of 25Mbps, making it suitable for high-speed industrial RS-485 and RS-422 communication links. This rate is achievable at the device's 3.3V supply voltage and applies to both the driver and receiver sections.
Which interface standards does the SN65HVD33D comply with?
The SN65HVD33D is compliant with EIA-422-B, TIA-422-B, EIA-485-A, TIA-485-A, ISO 8482, and ITU V.11 standards. This broad compliance allows the device to be used interchangeably in RS-485 and RS-422 networks and ensures compatibility with a wide range of industrial equipment worldwide.
What package type is the SN65HVD33D available in and what are the pin count details?
The SN65HVD33D is available in a 14-pin SOIC (Small Outline IC) package, JESD-30 code R-PDSO-G14. The compact surface-mount footprint makes it easy to integrate into space-constrained PCB designs typical of industrial control and automation boards.
Can the SN65HVD33D replace 5V RS-485 transceivers in existing designs?
The SN65HVD33D operates at 3.3V, whereas many legacy RS-485 transceivers use a 5V supply. Direct drop-in replacement is possible only if the system logic and bus biasing have been adapted for 3.3V operation. For 5V systems, TI offers pin-compatible devices such as the SN75HVD33D. Always verify supply voltage, driver output levels, and receiver input thresholds before substituting.
