Part Number: SN65C1168E

Hi All

My customer is using SN65C1168E for their 2ch RS422.
Then, they'd like to use same device for their 1ch RS422 too.

When they don't use the second driver and receiver of SN65C1168E,
how should they handle terminals?

Please advice

Best regards,
Honda.

Honda-san,
You can disable the driver by setting the second DE low and leave the output float. For the receiver, you can leave the inputs not connected. The internal bias sets the RX output high. Please let me know if you have more questions.
