Part Number: LSF0108

Dear Sirs or Madams,

Please let me know how we should treat unused I/O pins.

For example, if we don't use A8 pin and B8 pin, can we leave these pins floating?

Or, do we have to connect these pins to GND?

Best regards,

Hi Tanaka-san,
It's best to ground unused pins to prevent spurious signals from entering the system, however it is not required for the LSF0108. You can see how the device works in the Logic Minute video series located here: training.ti.com/logicminute

Dear Emrys san,

I appreciate your rapid response.

I understand it's best to connect unused I/O pins to GND although it is not necessary.

My question is resolved and I don't have further questions.

Best regards,
