Part Number: SN65HVD72 Tool/software: Hi team,
In customer system, Vcc can be off in order to reduce power consumption. While Vcc is off, current flows from A/B port to Vcc.
Is this expected behavior?
How do they prevent this?
Is this current flow no…
Part Number: SN65HVD72 This question is in relation to SN65HVD72: 5 Meter Communication design - Interface forum - Interface - TI E2E support forums
I would like to know if both sides of the communication need the 120 ohm and pull-up resistors, or if…
Part Number: SN65HVD72 Dear Specialists,
My customer would like to check if there is any example of SN65HVD72 communicating using the pulse transformer shown below.
I would be grateful if you could advise.
Are there any design example and adoption example…
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…

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…
