NJU7119
LOW POWER SUPER SMALL-SIZED
SINGLE C-MOS COMPARATOR
sGENERAL
DESCRIPTION
The
NJU7119
is super small-sized package single C-MOS
comparator with open drain output.
The operating voltage is from 1.8V to 5.5V. The output can
drive TTL, C-MOS and various voltage levels.
The input offset voltage is lower than 7mV and the
package is super small-sized SC88A. The
NJU7119
is
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 exceed the V
DD
level though
7.0V is limit specified.
Note2) The output pull-up voltage must not over the V
DD
level.
Note3) The power dissipation is value mounted on a glass epoxy board (FR-4) in size of 50x50x1.6
millimeters square.
Note4)
Decoupling capacitor should be connected between V
DD
and V
SS
due to the stabilized operation for
the circuit.
