ground
Low output saturation voltage: 250 mV typ;
(ISINK = 4 mA)
Differential input voltage range equal to the
supply voltage
TTL, DTL, ECL, MOS, CMOS compatible
outputs
Description
This family of devices consists of four
independent precision-voltage comparators with
an offset voltage specification as low as 2 mV
maximum for LM339A, LM239A, and LM139A.
Each comparator has been designed specifically
to operate from a single power supply over a wide
range of voltages. Operation from split power
supplies is also possible.
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.
