NE555是多用途集成时基块,以NE555为核心部件组成的8位数控脉冲发生器电路简单,稳定性好(不加恒温措施稳定性达2.5%),频率控制范围宽(可达130∶1).
The NE555 is a multipurpose integrated time base. The 8-bit CNC pulse generator with the NE555 as the core component has a simple circuit with good stability (2.5% stability without constant temperature) and a wide frequency control range (up to 130: ).
