The LM239DR is a four-independent Voltage Comparator, designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 to 36V and VCC is at least 1.5V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
0.8mA Typical low supply-current drain independent of supply voltage
25nA (typical) Low input bias current
2mV Typical low input offset voltage
Common-mode input voltage range includes ground
±36V Differential input voltage range equal to maximum-rated supply voltage
