SN55LVCP22A-SP: Unused differential input connections

Steve Widener

Part Number: SN55LVCP22A-SP

Tool/software:

I’m using a SN55LVCP22A-SP as a splitter. What do I do with the unused differential input? I’d assume I float it but what’s the recommended connection?

The inputs must not be left floating, and the two pins should not have the same voltage (but the input has some hysteresis, so it might work). Input voltages above 3 V are not recommended.

Hello,

I would recommend reading section 9.2.3.1 Design Requirements for reference.

Thank you,
Amy
