The LM2901 device is made up of four separate voltage comparators that can operate over a wide variety of voltages from a single power supply. Dual-supply operation is also conceivable, as long as the voltage difference between the two sources is between 2 and 36 V and VCC is at least 1.5 V higher than the input common-mode voltage. The supplied voltage has no effect on the current drain. To achieve wired-AND relationships, the outputs can be coupled to other open-collector outputs.
LM2901 Features
? Common-Mode Ground is included in the input voltage range.
? Differential Input Voltage Range is 36 V, which is equal to the maximum-rated supply voltage.
