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…

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…
Part Number: SN65HVD72
A recent counterfeit test report shows a very amateurish top marking on a batch of SN65HVD72
The TI logo is very vague in its outline, and all characters start with a pronounced white dot.
The Rear of the chip is not like any…
Part Number: SN65HVD72 According to a previous discussion, Tyler Townsend answered " It looks like these two waveforms show two different devices / drivers. The SN65HVD7x RS-485 transceivers do not have a built in offset as shown in the second scope…
Part Number: SN65HVD72 Due to the recent shortage of semiconductors, we purchased a quantity of sn65hvd72 parts offshore, and when used in conjunction of earlier production parts, we see an offset of the data (see pictures).
Although the data decodes correctly…
Part Number: SN65HVD72 Hi Team,
I use SN65HVD72 on one RS485 bus.
On one side of the bus (on the device)
when changing the nRE pin (from HIGHT to LOW and from LOW to HIGHT),
the Rx pin changes (LOW: duration 500ns)
It should be in a HIGHT state!
What…
