KODENSHI SN393

Low Power Dual Comparator
Semiconductor
SN393/P
Description
http:// www.auk.co.kr
The SN393 consists of two independent voltage comparators
designed to operate from a single power supply over a wide
voltage range.
Operation from split power supplies is also possible and the
low power supply current drain is independent of the magnitude
of the power supply voltage.
SOP-8
These comparators also have a unique characteristic in that the
input common–mode voltage range includes ground, even though
they are operated from a single power supply voltage.
