Operation of open drain outputs above 5 VDC m ay increase radio frequency emissions abov e permissible limits. Radio frequency c ontainment measures
may be required for your system or wiring.

Depending on y our pul se receiver and cable, an addi tional ex ternal pull up resistor may i mprove pulse signal qual ity and noise i mmunity.
