Part Number: SN65HVD1791 Hi, Good day. I hope you are doing well. On the SN65HVD1791D, table 7.1 indicates that the A and B lines are protected against over-Voltage, are the Y and Z lines also protected? Thank you. Regards, Cedrick
Part Number: SN65HVD1791 Could SN65HVD1791D be used as Half duplex RS485 by simply shorting
A-Y ----> Then using this as 'A' terminal for Half Duplex RS485
B-Z ----> Then using this as 'B' terminal for Half Duplex RS485
or is it not…
Part Number: SN65HVD1791 Hi expert,
Could you please let me know the ABS max for Y and Z pins?
I think the description in the datasheet is confusing.
I don't understand ABS max for HVD1791 Y,Z pin.

Part Number: SN65HVD1791 Having an issue with the output of the SN65HVD1791 steadily climbs to a higher reference voltage as pulses are being sent to the slave device. Reference voltage ramps back down to 0V when pulses stop. This is represented by the…

Other Parts Discussed in Thread: SN65HVD1791 Hello,
we are looking for a short application note / schematic how to design a uart (5V microcontroller Rx & Tx) to RS422 (one differential pair for Rx, one for Tx) full duplex Interface.
We found the SN65HVD1791…
Other Parts Discussed in Thread: SN65HVD1791 We are using the SN65HVD1791 with a VCC at 3.3V instead of the recommended 5V. It seems to work fine in the lab. Do you expect us to run into any problems working with this chip at a lower voltage?
Part Number: SN55LBC180 Other Parts Discussed in Thread: SN65HVD1791 , SN65HVD76
Q1: Can SN55LBC180 be used for RS422 application?
Q2: How to verify if a RS485 transceiver can be compatible with RS422?
The attach is the screenshot for the SN65HVD1791…
You're right that in general the A and B pins are somewhat independent and voltages on one shouldn't couple through to the other. In the case of a 28-V short-circuit, though, damage to the device would be likely (given that the absolute maximum…
