GENERAL DESCRIPTION
s
PAKAGE OUTLINE
The NJU6369 series is a C-MOS IC for fundamental quartz
crystal oscillator that consists of an oscillation amplifier,
5-stage divider and 3-state output buffer, and can oscillate at
1.5V very low voltage.
The 5-stage divider generates only one frequency selected
of f
0

/32 by internal circuits is output.
The oscillation amplifier is realized very low stand-by
current using NAND circuit.
The 3-state output buffer is C-MOS compatible.

) is less than 7.0V, the input voltage must not over the V
DD
level though 7.0V is
limit specified.
Note3) Decupling capacitor should be connected between V
DD
and V
SS
due to the stabilized operation for the
circuit.
