Part Number: SN75DP130

Hi Team,

Please allow me to clarify the power up sequence of SN75DP130DS.

I found the following post for SN75DP130DS power up sequence.

https://e2e.ti.com/support/interface/digital_interface/f/130/t/608397?tisearch=e2e-sitesearch&keymatch=SN75DP130

However, the datasheet states that Vddd must be ramped before Vcc.

Which is true ??

If, RSTN is only the requirement, please delete the statement which describes sequence of Vddd and Vcc.

Best Regards,

Kawai

Hello Kawai,

Thank you for your observation, we will edit the datasheet ASAP because is correct that the Vddd and Vcc time doesn't matter between them. The most important time is the RSTN.
