SE555D 芯片功能简介March 2007 Rev 4 1/2020NE555SA555 - SE555General purpose single bipolar timersFeatures■ Low turn off time■ Maximum operating frequency greater than 500kHz■ Timing from microseconds to hours■ Operates in both astable and monostable modes■ High output current can source or sink 200mA■ Adjustable duty cycle■ TTL compatible■ Temperature stability of 0.005% per °CDescriptionThe NE555 monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor.The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200mA.NDIP8(Plastic package)DSO8(Plastic micropackage)123456781 - GND2 - Trigger3 - Output4 - Reset5 - Control voltage6 - Threshold7 - Discharge8 - VCCPin connections(top view)

可以互换。只要它们的封装是一样的，引脚排列也一样。

555芯片具有多种功能，可以用做定时器、振荡器以及脉冲产生电路，在电子领域它是一个最重要、最流行的芯片。在单个晶体制作的集成芯片如同运算放大电路一样可靠、便宜。它能够产生稳定的方波信号，占空比从50%到100%。
