1
Operation of open drain outputs above 5 VDC may increase radio frequency emissions above permissible limits. Radio frequency containment measures
may be required for your system or wiring.
2
Depending on your pulse receiver and cable, an additional external pull up resistor may improve pulse signal quality and noise immunity.
