TI SN65HVD75 RS485 is not working while transmitting
I solved my problem.
I used TI SN65HVD75 RS485 and its operating voltage is 3.3V. And I tested it by Arduino UNO and MAX485 module. It works at 5V.
In MAX485 module there are pull-up and pull-down registers before A and B. But in my device there aren't registers before A and B.
I removed pull-up and pull-down registers in MAX485 module. After that my device can transmit datas and receive datas too.
