The LM139A, LM239A, and LM339A are precision voltage comparators with a wide single supply voltage range of +2V to +36V or ±1V to ±18V.
They have very low supply current, low input bias current, low input offset current, and low input offset voltage.
The input common-mode voltage range includes ground, and they have low output saturation voltage.
They are compatible with TTL, DTL, ECL, MOS, and CMOS outputs.
These devices can operate from a single power supply over a wide range of voltages and can also operate from split power supplies.
They are available in different package options and have various typical applications.
The electrical characteristics, absolute maximum ratings, and package mechanical data are also provided.
