Hello everyone! The post it’s not for a project, only a question out of curiosity.
I had used before a SN75176a differential bus transceiver in which I had inputted two bus signals to it. One signal was 0V to24V and the other -24V to 0V. The recommended operating conditions of the transceiver say that the voltage at any bus terminal should be min -7V and max 12V. When I used a voltage divider (for example 1Mohm and 400kohms gives +/- 6.86V) and I measured the voltage that would go into the transceiver, was much smaller, for example 1.5V (I don’t remember the exact value). Probably, the transceiver has its own resistor within and alters the value from the voltage divider? Is that normal or a problem and it would be better to use a voltage regulator in these cases? Without Transceiver voltage 6.86V, with Transceiver much less.
The transceiver was not burned, so either I was lucky or it’s normal :).
