LOW POWER AND LOW OFFSET VOLTAGE
SUPER SMALL-SIZED SINGLE C-MOS COMPALATOR
!
GENERAL DESCRIPTION
!
PACKAGE INFORMATION
The
NJU7118
is a super small-sized package single
C-MOS comparators with open drain output.
The operating voltage is from 1V 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 4mV
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.
