Globaltech GS391
The GS391 consists of a independent precision voltage comparator which was designed specifically to operate from a single power supply over a wide range of voltages. The comparator also has a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. The GS391 was designed to directly interface with TTL and CMOS.DESCRIPTION
Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. When operated from both plus and minus power supplies, the GS391 will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparator.
