PRELIMINARY
High Drive 3rd. Over Tone Quartz Crystal Oscillator
sGENERAL DESCRIPTION The NJU6378 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. Furthermore, the package is small-sized MTP-6. sFEATURES qOperating Voltage qOscillation Frequency Range qLow Operating Current qHigh Fan-out sPACKAGE OUTLINE
