Frequently Asked Questions
What ESD protection level does the THVD1450DRBT provide?
The THVD1450DRBT provides ±18-kV IEC ESD protection on its bus pins, significantly exceeding the typical ±8-kV HBM level, which helps prevent damage from electrostatic discharge events during installation and field operation.
What supply voltage range does the THVD1450DRBT support?
The device operates from a 3.3-V to 5-V supply, allowing it to interface with both 3.3-V logic systems and legacy 5-V systems without additional level-shifting circuitry, simplifying mixed-voltage board designs.
Which interface standard does the THVD1450DRBT comply with?
It complies with EIA-485-A and TIA-485-A standards, making it fully interoperable with any RS-485 or RS-422 network equipment on the same bus, including PLCs, HMIs, and serial converters.
What package is the THVD1450DRBT available in?
The THVD1450DRBT comes in an 8-pin Small Outline No-lead (SON/VSON) package coded JESD-30 S-PDSO-N8, which offers a small PCB footprint and good thermal performance compared to traditional SOIC packages.
Is the THVD1450DRBT RoHS compliant?
Yes, the THVD1450DRBT carries a Pb-free code of 'Yes' and JESD-609 code e3, confirming it meets RoHS requirements and is manufactured without lead, making it suitable for environmentally conscious designs and EU-market products.
