Part Number: SN65HVD1471 Tool/software: Hi
We are using the SN65HVD1471D in an RS-485 bus where we intend to operate it in half-duplex mode (same differential pair for TX and RX). We have externally shorted the Y to A and Z to B to create a shared bus…

Part Number: SN65HVD1471 Other Parts Discussed in Thread: SN65HVD1474 Hi experts
I would like to know if this device can be used for signaling above 400kbps, for example at 950 or 1000 kbps.
I have an application that I am already using it at a higher…
Part Number: SN65HVD1471 Hi, I met a problem when i tried to interface my SN65HVD1471 transceiver with MAX14850 isolator. Please refer to my connection below,
R(Transceiver) - INA1- OUTB1 - Rx(MCU)
Tx(MCU) - INB1 - OUTA1 - D(Transceiver)
Transceiver…
Part Number: SN65HVD1471 Hi,
SN65HVD1471 transceiver IC produces irrelevant output. To check hardware i just shorted Tx and Rx pins of IC and connected the differential pair by connecting 120 ohms across A,B and Y,Z, and given 3.3V to vcc pin and connected…
Part Number: SN65HVD1471 Hi,all
The SN65HVD1471 device can be used for RS-422 interface? I cann't find the datasheet said it can support RS-422 interface.
Is there any reference design for RS-422?
Part Number: SN65HVD1471 Dear sir,
i bought SN65HVD1471, for communicating PIC18F65K40 using RS422 protocol. I can't able to understand, how it's interfacing with DB9 connector and also where to drive output and to give input in this transceiver IC…
Hi,
Termination resistors should be used between each differential pair (A to B and Y to Z) at each cable end (first and last device on the bus). See section 10.1, figure 30 on the datasheet. The value of these resistors should match the characteristic…
Rajesh,
You can consider SN65HVD1471, which has better ESD protection but might not be enough for the surge current. What's your schedule of product release? We're developing some RS485 transceivers with surge protection feature. You could evaluate them…
Hi Ray,
SN65LBC184 as a p2p replacement for the MAX483ECPA+ will work. LBC184 has more input voltage range on the RS-485 bus, and has similar drive strength to the MAXIM device. The cross-reference tool will always choose more updated parts (THVD1410…
