OPTIONS
suffix "N" = Negative Logic Enable (without suffix “N” designates Positive Logic Enable)
suffix “6” = 3.7mm pin length (5mm nominal default pin length)
suffix “-3” = single pair of output pins (Pins 4 and 10 unstuffed)
without suffix “-3” = double pair of output pins (Pins 4,5, 9 and 10 are present)
suffix “L” = RoHS compliant (RoHS 6) / “Blank” = RoHS compliant with Lead (Pb) in solder exemption (RoHS 5)
