DESCRIPTION
The LM139 series consists of four independent
precision voltage comparators with an offset voltage
specification as low as 2 mV max for all four
comparators. These 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.
Application areas include limit comparators, simple
analog to digital converters; pulse, squarewave and
time delay generators; wide range VCO; MOS clock
timers; multivibrators and high voltage digital logic
gates. The LM139 series was designed to directly
interface with TTL and CMOS. When operated from
both plus and minus power supplies, they will directly
interface with MOS logic— where the low power drain
of the LM139/LM139A is a distinct advantage over
standard comparators.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
