NE555DT

◇ 产品简介 ◇

  TheNE555monolithic timing circuit isa highlystable controller capableofproducingaccuratetime delays or oscillation.In the time delay mode of operation,the time is p-recisely controlled by one external resistorandcapacitor.For astable operation asano scillator,the free running frequency and the duty cycleare both accurately contro-lled 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 TheNE555 is available in plastic and ceramic minidip packageand in a 8-leadmicropackage and inmetal can package version.
