Hi,
the device you're planning to use has been used in many e-meter applications before as you can find on ti.com. In fact due to a wide common-mode range and high ESD-protection levels, these devices are well suitable for applications such as energy…
Hello,
I'd recommend looking into THVD1500 as an initial suggestion. It is similar to SN65HVD3082E but has higher ESD ratings, lower ICC, and supports a wider temperature range. I'm not qualified to make any guarantees with respect to long-term production…
Hi Antonio,
as you probably know the number of nodes depends on the current that the device can outsource which can also be seen from a resistance perspective, that is there is a limit on the maximum resistance that can be driven. In order to increase…
Hi Wesley,
One thing that is common for many HVAC applications is that they could involve a large number nodes operating at lower data rates but communicating over relatively long distances across cabling networks that are not ideally routed (due to…
Part Number: SN75176B Other Parts Discussed in Thread: SN75HVD07 , SN75HVD06 , SN75176A , THVD1500 We are going to make a product for sale in series with 256 RS485 networked devices a 9600 bps, 4000 ft and half duplex. I read some topics about RS485 network…
Hi Jeff,
Thanks for the waveforms and further description! This really helps clear things up.
Where are you seeing that the receiver output should be high when /RE is low and the bus input is left open? Per the Receiver Function Table (Table 3 on…
Takanori,
I would suggest that you look at the THVD15XX family of devices. Depending on your speed requirements, you should find a good match for your application.
THVD1552: Full duplex, <50Mbps
THVD1512: Full duplex, <500Kbps
THVD1500: Half Duplex…
Dear Hao,
many thanks for the reply.
The article you mention above " How to choose TVS diodes " is the one that confused me initially.
Although the text was clear, the example with the SM712 and the THVD1500 was not.
Of course, according to your…
Hi Daniel,
The SN65HVD485E is an RS-485 transceiver, which means that it can be used to translate between single-ended logic-level signals and RS-485 bus signals. A typical application is to connect the device's logic I/O (D, R, DE, and RE) to a UART…

Question from a customer-
Several years ago we designed a new processor board with a touchscreen…
