THVD1424: schematic check

Hi Tommy,

Here are my comments for this schematic:

• Double check the NC (no connect) resistors.
  • TERM_TX currently is floating without the 0 Ohm resistor. This is fine as TX termination will be disabled by default. 
  • Z/Y bus pins are also not connected. This means that only A and B receiver pins will work in full duplex mode. 
• H/F pin is pulled high so half duplex mode is enabled. 
• Consider adding a pullup resistor on the R pin so it has a default state while the RXD pin is high impedance while the receiver is disabled. 

Best,

Ethan

Hi Tommy,

That looks good now. They have corrected everything that I pointed out.
