General Description
LM139,A General Description
These devices consist of four independent precision voltage comparators with an offset voltage specifications as low as 2mV max for LM339A,LM239A and LM139A. All these comparators were designed specifically to operate from a single power supply aver 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.

1. Short-circuits from the output to VCC+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20mAindependent of the magnitude of VCC+
2. Pd is calculated with Tamb = +25°C, Tj = +150°C and Rthja = 80°C/W for DIP14 package
= 150°C/W for SO14 package
= 175°C/W for TSSOP14 package
