I am using a fail-safe transceiver, however since this device is just a repeater/converter meant for existing industrial networks I have no control over the driver architecture of any of the connected devices and deal often with pretty old legacy PLC's that may require a bias but do not contain...
I looked at the MAX13450 when i was initially designing the prototype, it has switchable termination but not bias. I am thinking of using a CMOS switch such as the
SN74LVC1G3157 but am a little concerned with possible over voltages exceeding the 5V rail of the analog switch (RS485 is spec'd to...
I am actually using digital isolators not optos because the power consumption is much better and this needs to be as low power device as possible. The digital isolators have logic outputs...
Hello,
I am tying to come up with a circuit to allow me to switch some pull up and pull down resistors in or out of the circuit on some differential signal lines (RS485 fail safe bias resistors). I need to get the enable for the pull ups across a opto to my isolated driver circuitry. Is there a...
