NJU6377 Series
3rd. Over Tone Quartz Crystal Oscillator
s
GENERAL DESCRIPTION
s
PACKAGE OUTLINE
The NJU6377 series is a C-MOS 3rd. over tone quartz
crystal oscillator that consists of an oscillation amplifier and
3-state output buffer.
The type numbers are classed into three versions E, F, G
and H according to their oscillation frequency range
mentioned 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.

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.
