SN65LVCP23: Unused input pins

Kei Kuwahara

Part Number: SN65LVCP23

Tool/software:

Hello team,

What should I do for the unused input pin?
Should I connect it to GND or VCC?
If so, could you please give me recommended pull up/down resistor value?

I would like to use as configuration below.

Best Regards,
Kei Kuwahara

Hello Brian-san,

The input signal is LVPECL.

Does the input signal have any effect on unused input pins?

HI Kei:

the input signal have no effect on unused input pins.

IN1 is another differential channel, it can be floating if unused.
