Low power dual voltage comparator

DESCRIPTION
The LM193 series consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0mV
max. for two comparators which were designed specifically to
operate from a single power supply over a wide range of voltages.
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. These comparators also have a unique
characteristic in that the input common-mode voltage range includes
ground, even though operated from a single power supply voltage.
The LM193 series was designed to directly interface with TTL and
CMOS. When operated from both plus and minus power supplies,
the LM193 series will directly interface with MOS logic where their
low power drain is a distinct advantage over standard comparators.
