Part Number: SN65HVD82 Other Parts Discussed in Thread: THVD1550 , THVD1500 , SN65LBC184 Hi Team,
I am Shawn, AE of MCP, I am rotating in south China FAE Team.
We meet an issue of RS485, customer use SN65HVD82 to communicate with USB 485 debugger…
Hi Gim,
The maximum ICC for SN75176B when the outputs are disabled is 35 mA. A better device for low-power applications would be THVD1500. Its maximum standby current is just 1 uA. Please let me know if you see any issues with that device.
Regards…
Hello,
I'm unfortunately not aware of any pin-to-pin replacements that would be available in the "PS" package. You may want to consider THVD1500, which is functionally equivalent and has the same pinout but smaller form factor (SOIC package). For higher…
Hi Daniele,
Figures 19 through 42 in the datasheet are a useful reference on how to set the various control inputs to correspond to different transmit and receive channel configurations. Once you have this determined, the device is relatively straightforward…
Hi Puneeth,
The THVD1500 device seems like a good option here. It does have a receiver built in as well, but this would not need to be used in a unidirectional (transmit-only) application. (You could just leave the R output disconnected and pull the…
Hi Wayne,
When the RS-422 interface is floating, the input differential voltage to the transceiver will be close to 0 V. This is also where in the input switching threshold is set, so small fluctuations in the pin voltages (due to noise, etc.) could…
Dear Max,
Thanks for your reply and suggestion.
We have checked resistances of working and non working IC's and found bus resistance and supply pin resistance wrt Gnd is changed. Below table for your ref.
Pin Resistance wrt Gnd Ok IC Not Ok IC 1…
Hello Akaba-san,
Yes, there is no issue for the SN65176B when tying DE to VCC (5 V). However, this should only be done if your application involves simplex (uni-directional) data transfer. If the SN65176B will need to receive data from other nodes …
Hi Fred,
We unfortunately do not have a dual driver at this temperature range. One option would be SN65C1168, which is rated to 85 C but has two receive channels which you will not use. Another option would be using two THVD1500 devices. Again this…
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…
