Part Number: SN65HVD72 Other Parts Discussed in Thread: THVD1419 Hi
I would like to use SN65HVD72 for an upcoming project, where we will have our main PCB, and the secondary PCB could be max 5 meters away.
We would like simple UART communication between…

My customer is having an issue where an RS485 bus appears fully functional for several hundred hours, but begins to miss pings and quickly loses communication entirely. The receiving device has a 24V pump that seems to increase…
Part Number: SN65HVD72 Hello TI forum -
I have an application that incorporates 500 SN65HVD72 devices on a RS485 bus. The bus consists of 1000' 24AWG 120ohm twisted-pair cable with drops every 2'. Data rate is 115.2kbps. Terminations on both ends are…
Part Number: SN65HVD72 Other Parts Discussed in Thread: MAX3221 , SN74AUP2G17 , THVD1426 , THVD1406 I have an rs232 communication line that I have been communicating directly to an esp32. Recently I decided to include a SN65HVD72DR for a little added protection…
Part Number: SN65HVD72 Other Parts Discussed in Thread: THVD1406 Hi Sir,
SN65HVD72DR
Due to the insufficient MCU GPIO to control DE and RE pins, I propose using a TX with BJT to control DE and RE.
below is my RS485 schematic for your reference. if any issue…
Part Number: SN65HVD72 Hi all,
We have been experiencing issues with a design using SN65HVD72 RS485 transceivers. The R line is not behaving to the datasheet, so when the bus is idle it is going low instead of remaining high. This is creating phantom…
Part Number: SN65HVD72
Hi team,
We are using SN65HVD72DRBT in our product with the 40mA PPTC on the Differential line.
We need to analyze the short circuit behavior of the Differential Bus with and without termination and failsafe resistors.
As, I got…
Part Number: SN65HVD72
Hi team,
We have designed an RS485 device that will act as a slave device, as per the attached schematic,
Please suggest your inputs on the bus termination resistor R20 and R26, and their overall impact on the network when ~32 devices…
Part Number: SN65HVD72 Dear
I want to suppose a issue from my customer:
Application: SN65HVD72 is used for the RS-485 application, and my customer wants to use the TVS protection circuit, which is the same as the Fig.27 in the datasheet.
Problem: The…
Part Number: SN65HVD72 I would like to know if the internal structure of this component (in X-Ray) could be different depending on the COO or the revision of the die.
I have found different structures for this component and I wpuld like to know if it…
