TL16C2550　unused pin

PAN-M

Our customer use only RS/CS flow (RXD,TXD,RTS,CTS)
In this case, How should the unused pin be tied? (CD,DSR,RI,DTR,OP,TXRDY,RXRDY)
Input=Low, Output=open
Is it correct?

Regards,

Hi PAN-M,

My group does not support this device, so I am going to move your thread to the consumer and computing forum so that it can get the right visibility and support. Thank you for your question.

From a quick search on E2E the thread below may help with a few of the open pin connections:

Hello Pan,

All he inputs may be tied to low with the exception of RIA, RIB DSRA & DSRB , since these terminals are active low (unless you wanna have them active).

Rest Regards,

Diego.
