Otherwise, you can look at an auto…
Other Parts Discussed in Thread: THVD1400 , THVD1406 , THVD1426 Dear support team, I need a RS485 transceiver IC with auto-direction control. I have two principle questions in this context: Question 1) About low 9600 baud rate, auto-direction control and fail…
Hi Surya,
The THVD1426 is most likely the best fit for your application.
It works very similarly to your current setup.
By tying /RE and /SHDN to logic high the device will be in auto-direction mode.
1. The device will output on A/B following inputs…

Part Number: TRS3232E Other Parts Discussed in Thread: THVD1426 , THVD1406 Hi,
Plesae kindly advise if there are any deivce to i mplement the RS232 to RS485 interface, or there are any soluton to realize it, thanks.
You must not connect two active push/pull output pins together. This happens for the R pins. Either replace U17 with a transceiver that has an RE input (and ensure that at most one RE is high), or combine the two R outputs with an AND gate, or insert…
