1. Short-circuit from the output to VCC
+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20mA, independent of the magnitude of V_CC + .
2. Pd is calculated with Tamb = +25°C, Tj = +150°C and
Rthja = 80°C/W for DIP14 package,
Rthja = 150°C/W for SO-14 package,
Rthja = 175°C/W for TSSOP14 package.
3. Human body model, 100pF discharged through a 1.5k resistor into pin of device.
4. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external series resistor (internal resistor < 5), into pin to pin of device.

Description

This LM2901N consists of four independent precision voltage comparators. All these comparators are designed specifically to operate from a single 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.
