Voltage detector by IC TL431

This be simple check pressure level circuit, with integrated number circuit TL431. When use power supply 5Volt in digital circuit. The general feeding signal input be high class logic be High, make have voltage way output be 5 Volt. But enough feed the level logic be Low as a result, make output level voltage be 1.8V this circuit uses the equipment a little 2 pcs. only just as a result can be usable already.
