comparators

with

an

offset

voltage

specification as low as 2 mV max for all four

•

Very Low Supply Current Drain (0.8 mA) -

comparators. These were designed specifically to

Independent of Supply Voltage

operate from a single power supply over a wide range

of voltages. Operation from split power supplies is

voltage. These comparators also have a unique

•

Input Common-Mode Voltage Range Includes

characteristic in that the input common-mode voltage

range includes ground, even though operated from a

GND

single power supply voltage.

•

Differential Input Voltage Range Equal to the

Power Supply Voltage

Application areas include limit comparators, simple

analog to digital converters; pulse, squarewave and

Low Output Saturation Voltage: 250 mV at 4

time delay generators; wide range VCO; MOS clock

mA

timers; multivibrators and high voltage digital logic

•

Output Voltage Compatible with TTL, DTL,

gates. The LM139 was designed to directly interface

ECL, MOS and CMOS Logic Systems

with TTL and CMOS. When operated from both plus

and minus power supplies, they will directly interface
