Part Number: THVD1400 Tool/software: Hello,
Inputs 'Re_bar' and 'De' are internally tied to Vcc and GND respectively but the 'Re/De' short is pulled down to GND.
The effect of 'DIR' driving a '1' or a '0' is clear. …
Part Number: THVD1400 Tool/software: What is the VOH and VOL range for the THVD1400DR on the RS422 side? I know it is just RS422 standard, but I am having hard time finding the voltage logic range. I hope this is a simple question.

Hello E2E Community,
We are trying to improve the Surge & Transient immunity of our sensor nodes that are interfaced using THVD1400.
We have a TVS diode with following specifications - based on your expert knowledge…
Part Number: THVD1400 Tool/software: When THVD1400DR is disabled or when no power is applied to it, what is the output impedance on its pin 7 and pin6 B and A pins? The datasheet says "high impedance". I am asking on this forum to see if there is a more…
Part Number: THVD1400 Tool/software: Hi All,
I have a question about the THVD1400. The maximum rated voltages of inputs A and B are as follows, so I understand that it is input tolerant. Is my understanding correct?
Best Regards, Ishiwata
Part Number: THVD1400 Other Parts Discussed in Thread: SN65HVD75 Tool/software: HI,
The customer uses THVD1400 as the RS485 transceiver. Feedback power consumption is high and cannot meet the demand. Is there a recommended product with better power consumption…
Part Number: THVD1400 Tool/software: Hi there,
I hope you are doing well!
There is doubt on interfacig MCU ie ESP32 withTHVD1400 operated with different voltage levels. Altough there is no issue incurred for being tested a month now. But for the long…
Part Number: THVD1400 Tool/software: Hi
I am using this THVD chip and I am trying to reduce current on my design.
currently I have 1mA current flowing through R44. even when there is no power on the RS485.
I was trying some solution in order to reduce…
