SN65HVD1781: Clarification on Operating Voltage

Part Number: SN65HVD1781

Tool/software:

Hi Team,

I'm planning to use the SN65HVD1781D in one of my 3.3V systems. While reviewing the datasheet, I noticed that under the Features section, it mentions support for 3.3V or 5V systems. However, in the Pin Description table, the supply voltage (Vcc) range is listed as 4.5V to 5.5V.

This has caused some confusion—could you please clarify whether the device can be operated reliably in a 3.3V system?

    Hi Nathan,

    The device's warranty is based on the recommended operating conditions. For Vcc, this device accepts a 3.15V min and 5.5V max. The device's typical (kinda like what it was designed around) is 5V. The short answer is yes, this device supports 3.3V supply but there might be some parameters that are affected by 3.3V vs. 5V uses.

    Example is the operating max temperature TA is lower for 5V and higher for 3.3V. Also see the VoD spec as another parameter that changes with Vcc.
