Part Number: TRS3232 Hi,
Customer met an issue when use TRS3232, they found there is a saw noise coupling with output voltage. Please see pictures below. Could you please help me analysis the reason behind, thanks.
with load,
without load,
Part Number: TRS3232 what's the best, when only one channel of TRS3232 is used, connect the second channel inputs to ground or just leave them floating?
Part Number: TRS3232 Dear all,
I would like to ask how to handle unused pins.
Of the two input / output channels of TRS3232, one circuit is unused.
Please tell me how to handle unused pins DIN, Dout, Rin, Rout.
I checked the data sheet, but there was…
Part Number: TRS3232 Hi
I read the following articles to understand the operation of internal charge pump.

Hi Hao,
I understand what you are talking.
I was same understanding as you answer before. But now V+ does not go up to 2*VCC. V+ is clamped bellow 6~7V by TRS3232.
So C1 is only charged 1~2V at B region (at above waveform).
At B region , C1+ is (of…
Part Number: TRS3232 Hi Team,
Our customer is using TRS3232 device and changes design from 5Vcc to 3.3Vcc. Can this change in supply from 5V to 3.3V, create any impact on lines RIN (13 th pin) and DOUT(14 th pin). Is there any variation on voltage levels…
Part Number: TRS3232 Other Parts Discussed in Thread: , STRIKE Dear E2E,
Customer use TRS3232 device on their system. They did 4kv ESD test. After that, they could see the error code through RS232 port.
Does team see the similar issue before and how to…
Part Number: TRS3232 Hello,
We couldn't buy the capacitor which is written in datasheet due to capacitor shortage.
The use condition is below. We can't buy 0.047uF capacitor so we are wondering if 0.1uF can be used for alternative part of 0.047uF.…
Part Number: TRS3232 Hi
Our customer are considering to add the external protection diode to RIN1/2 and DOUT1/2 pin.
I understand the benefit of this device is having ESD protection internally.
On the other hand, I am concerned how to connect the external…
