SLCS005Z - OCTOBER 1979 - REVISED OCTOBER 2017 LM393, LM293, LM193, LM2903 Dual Differential Comparators
1 Features 3 Description •
• These devices consist of two independent voltage
comparators that are designed to operate from a
single power supply over a wide range of voltages.
Operation from dual supplies also is possible as long
as the difference between the two supplies is 2 V to
36 V, and VCC is at least 1.5 V more positive than the
input common-mode voltage. Current drain is
independent of the supply voltage. The outputs can
be connected to other open-collector outputs to
achieve wired-AND relationships. 1 •
