Part Number: SN65HVD1781A-Q1 Tool/software: I am using the IC "SN65HVD1781A-Q1" for converting the UART to RS422 signal using the microcontroller P/N. TMS320F28335ZJZQ.
as per data sheet, suppose to get the loopback signal from the pin 1 (R-Receive…
Part Number: SN65HVD1781A-Q1 Tool/software: Is it okay to control the DE pin and RE pin in opposite directions by connecting the DE pin and RE pin to the OPEN collector node of the NPN TR and controlling the TR BASE through one GPIO of the MCU?
GPIO…
Part Number: SN65HVD1781A-Q1 Tool/software: If you input a HIGH value to the DE pin, you can activate DATA, and if you input a LOW value to the RE pin, you can activate Receive. According to the data sheet Application Information, there is a way to use…
Part Number: SN65HVD1781A-Q1 Tool/software: Hello e2E Experts,
Good day.
1) Can you confirm that the driver and receiver of the SN65HVD1781A-Q1 can be enabled simultaneously for verification of the data transmission by loopback to Controller?
2…
Part Number: SN65HVD1781A-Q1 Tool/software: Hi Bobby,
Just checking to see if you had an update on the status of the approval process for the datasheet. Thanks.

Part Number: SN65HVD1781A-Q1 Tool/software: The minimum temperature specification for both operation and storage in the datasheet is -40C. Is this correct, or is there additional margin for the storage temperature value (I would expect something along…
Part Number: SN65HVD1781A-Q1 Tool/software: Hello,
We have an ASIL B ECU design project with the need for a RS-485 transceiver. If not wrong, we think you don't have andy ASIL B transceivers available, the best fit we found is this one, that is safety…
Part Number: SN65HVD1781A-Q1 Tool/software: I am using SN65HVD1781A-Q1. However, how can I calculate the pull-up and pull-down resistance values in the RS-485 A port and RS-485 B port that are connected to the outside? Please provide the calculation…
Part Number: SN65HVD1781 Hello,
Got two short questions above the devices in the title: Beyond the automotive -Q1 rating and slightly different operating temperature & ESD ratings, are there any functional differences between these two devices?
