Other Parts Discussed in Thread: THVD1451, THVD1450
I want to use SN65HVD78D to realize serial port to RS485. There are the questions about the connection of device pins.
The Pin1 of sn65hvd78D is connected to RX, and the pin4 is connected to TX.
How do Pin2 and PIN3 connect? Are these two pins connected directly?
