Hi TI,

Using SN65HVD75 2EA, I want to use RS-422 communication.

/ RE, and DE pin to Pull-up or Pull-Down.
(Ie, one of the two ICs is Tx, the rest is fixed at Rx).

Thank you for your help.

Hi BJ,

Yes, this will work.

Transmit IC: Pull DE and /RE pins to VCC through a Pull-Up Resistor.

Receive IC's: Pull DE and /RE pins to GND through a Pull-Down Resistor.

Regards,
Jonathan
