NJU7109
LOW POWER SUPER SMALL-SIZED
SINGLE C-MOS COMPARATOR
sGENERAL
DESCRIPTION
The
NJU7109
is super small-sized package single C-MOS
comparator with push pull output.
The operating voltage is from 1.8V to 5.5V, and the
interface can be connected with most of TTL and C-MOS type
standard logic ICs.
Furthermore, The input offset voltage is lower than 7mV
and the package is super small-sized SC88A, therefore they
can be suitable for battery use items and other portable items.

Note1) If the supply voltage (V
DD
) is less than 7.0V, the input voltage must not over the V
DD
level though 7.0V
is limit specified.
Note2) The power dissipation is value mounted on aglass epoxy board (FR-4) in size of 50x50x1.6 millimeters
square.
Note3) Decoupling capacitor should be connected between V
DD
and V
SS
due to the stabilized operation for the
circuit.
