NJU6370 Series
High Drive 3rd. Over Tone Quartz Crystal Oscillator
s
GENERAL DESCRIPTION
s
PACKAGE OUTLINE
The NJU6370 series is a C-MOS 3rd. over tone quartz
crystal oscillator that consists of an oscillation amplifier and
3-state output buffer.
The NJU6378 series has 4-types according to their
frequency ranges as shown in the line-up table.
The oscillation amplifier is realized very low stand-by
current using NAND circuit.
The 3-state output buffer is C-MOS compatible and can
drive 50pF(@5V) C-MOS load.

) 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.
