Description

TSSOP14

(Thin shrink small outline package)

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.

QFN16 3x3

(Plastic micropackage)

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.
