GM339
LOW POWER QUAD
DIFFERENTIAL COMPARATOR
Description
The GM393 consists of four independent
precision voltage comparators which were
designed specifically to operate from a single
power supply over a wide range of voltages.
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. 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.
Application areas include limit comparators,
simple analog to digital converters; pulse,
square wave and time delay generators; wide
range VCO; MOS clock timers; multivibrators
and high voltage digital logic gates. The GM339
are designed to directly interface with TTL and
CMOS. When operated from both plus and
minus power supplies, the GM339 will directly
interface with MOS logic, where their low power
drain is a distinct advantage over standard
comparators.
The GM339 is available in DIP-8 and SOP-8
packages.
