... Schmitt trigger that eliminates switching uncertainties. Both types include two complementary high current switched outputs for driving power transistors requir- ing up to 120mA. The CA3165E also includes two comple- mentary low current outputs that incorporate internal current limiting and a non-inverting output amplifier with uncommit- ted input capable of switching 27mA ...
