Hi Mason,
Please take a look at THVD1550, which is a pin-for-pin replacement with performance improvements with respect to VCC range and noise and ESD immunity. If you have any questions or feedback on the device, please let me know.
Regards, Max
Hi Supriya,
The schematic didn't come through; could you please re-post it?
Do you mean that you apply 5 V to the VCC pin of the SN65HVD75 device? This is not recommended. It was designed for VCC = 3.3 V. We have other transceivers designed to support…
Jack,
SN65HVD3088E might be a better choice here. Do you care IEC ESD spec? You can also check out TI newly released THVD1550, which is top notch in ESD protection.
Regards,
Hao
Thanks for the picture. I think the reason is over-the-limit current flows into the resistor and IC. You can try with TVS diodes, resistor and IC with higher ESD protection rating. For your information, THVD1550 is rated with +/-18kV IEC 61000-4-2 ESD…
I would add as well that if you are looking for a p2p transceiver IC with higher temperature support, you may want to consider THVD1500 or THVD1550 (depending on the application's data rate).

Hello,
Unfortunately I am not aware of any SPICE model developed for DS75176B. The closest available model would be for SN65HVD1786, which is also an RS-485-compliant transceiver:

We also have…
Hi Cedrick,
Agreed that the VID requirement of 0.5 V is relatively high, but keep in mind this IC was designed in the early 1970s. :) From Figures 7 and 8 in the datasheet you can see the typical VID threshold and how it varies with different conditions…
Part Number: TL16C754B Other Parts Discussed in Thread: AM3352 , THVD1550 , TL16C752D , TL16C754C Hi Team,
My customer is using AM3352 in their new DCS communication project. As UART is not enough, we penetrated 2pcs TL16C754B to extend the UARTs, but…
Hello,
Previously I had provided some data on an unreleased transceiver. That device has now officially released, and so you can find more information on it here:

Hi Benjamin,
The input high/low switching threshold for SN75176B is near 0 V, so if the signal is held near this threshold even a small amount of coupled noise could result in toggling on the R output. That seems to be what is happening here. The easiest…
