The 3V to 18V supply range spans legacy 12V industrial rails and modern 3.3V logic, making it a drop-in for mixed-voltage BOMs without a level translator. The 4000B series is known for wide noise margin at higher supply voltages, so at 12V or 15V the switch thresholds stay clean in a noisy backplane.
