AM26C32: Treatment for unused pin

Part Number: AM26C32

Hi,

Could you please let me know how to treat unused input pin? Can it leave open? or short it to GND?

Regards,
Nagata.

    Unused outputs can be left open.

    The A and B inputs have internal pull-up/-down resistors and can be left open. The G and /G inputs always must have a valid voltage; connect them to VCC or GND as needed.

    Hi Nagata,

    I agree with what Clemens stated. 

    Here is a figure from the datasheet that shows the internal pull-up/down resistors of the A and B inputs:

    With G and /G, connect them to VCC or GND as needed, do not leave them floating. 

    Regards,
