LM339ADT STMicroelectronics, Quad Comparator, CMOS/TTL O/P, O/P, 300ns 2 → 36 V 14-Pin SO14

The STMicroelectronics Low power quad voltage comparator consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV. This comparator is designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible.

Very low supply current independent of supply voltage
Input common mode voltage range includes ground
Low output saturation voltage
Differential input voltage range equal to the supply voltage
TTL and DTL compatible outputs
MOS and CMOS compatible outputs
