Part Number: SN74LVC1G123 Other Parts Discussed in Thread: TIDA-060008 Should CEXT (pin 6) be connected to GND? In the TIDA-060008 it is connected to GND but the datasheet is only to one of the capacitor ends.

Hello, I'm trying to reproduce the TIDA-060008 circuit but with THT components (and without the optoisolator). I replaced the TRS3232 component by the ICL3232…
Part Number: TIDA-060008 I have followed the TIDA-060008 reference design to make a simple, but isolation protected RS232 to RS485 board. However, I am seeing no output from the A or B on the RS485 Transciever. I do see signal on the OUTC (Pin 5) of the…
Part Number: TIDA-060008 Not getting any output from RS485 Transceiver, but I do see input on D (Pin 4) of the Transceiver. Not sure of utility of the DIN1 and DIN2 jumpers and the need for the Multivibrator.
Any help is appreciated to get a basic circuit…
Hi Nison,
Do you mean a way to convert between RS-485 and RS-232 signalling? If so, you can find an example circuit (using a half-duplex RS-485 implementation) here:

For point-to-point applications you could also implement…
Hi Lilian,
Typically you would need one transceiver to handle the RS-485-to-TTL conversion and another transceiver to handle TTL-to-RS-232 conversion. If the link is half duplex, you may need additional logic circuitry to properly control the RS-485…
Hello Shu-Cheng,
There are a couple of different approaches for automatically controlling the direction of the RS-485 transceiver. The MAX13487 device implements this by only actively driving the low signal level and going high-Z for high levels (making…
Part Number: SN75176B Other Parts Discussed in Thread: SN74LVC1G07 , , THVD1520 , THVD1426 , THVD1552 , THVD1551 Hi there,
Good day.
This is a product project I'm working on. I want it to be able to provide two different interfaces (RS485 and RS422) and have…
