SN65HVD54:電源供給ピンについて

Tomoki Furuya

Part Number: SN65HVD54

他社のデバイスからSN65HVD54Dへの置き換えを検討しており、各ピン配列は同等なのですが、
既存部品は13ピンがN.Cになっています。
その為、SN65HVD54Dに置き換えた際に13ピンはN.Cで14ピンからしか電源が
供給されない状態になるのですが、この状態で使用するのは特に問題は
ないでしょうか。

Hi Tomoki,

I am sorry - but after translating the text - I am unsure what the question is. Can you please rephrase your question so I can help support you? I apologize for the inconvenience.

Best,

Both V_CC pins must be connected. If you use only one, then the power supply connection will not be as good as it was designed, and the electrical characteristics are no longer guaranteed.

In practice, I guess that there will not be much of an effect. But you will have to do your own tests, and as I said, there are no guarantees.
