NE555N

TIGER ELECTRONIC CO.,LTD S ingle T imer N E 555 N / N E 555 D DESCRIPTION T he N E 555 N / NE 555 D i s a highly stable c ontroller capable of producing accurate tim ing p ulses. With a m onostable operation, the tim e d elay is c ontrolled by o ne external resistor and one c apacitor. With an astable operation, the f requency and duty cycle are accurately c ontrolled by t wo external resistors and one c apacitor.
