DS26C32AT: Unused terminal

Kenji Nishiyama

Part Number: DS26C32AT

Tool/software:

Hi,

We have some qestions for handling unused terminals of DS26C32AT.
1.How to handle the input pins (A input, B input) of unused elements. Pull down or Pull up or open?
2.If there is no termination resistor, can both the A and B inputs remain OPEN?

Best regards

As shown in the truth table on p. 6, open inputs are allowed and result in a high output.

"Open" means "no termination" and is the simplest solution. But if you have a termination resistor, then you must also add fail-safe pull-up/-down resistors.
