Offset Voltage: ±3 mV

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.

Input Common-Mode Voltage Range Includes

GND

•

Differential Input Voltage Range Equal to the

Power Supply Voltage

Low Output Saturation Voltage: 250 mV at 4

Output Voltage Compatible with TTL, DTL,

ECL, MOS and CMOS Logic Systems

ADVANTAGES

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
