TIMER USM LM 555 FEATURES APPLICATIONS VOLTAGE REGULATOR Direct replacement for SE555/NE555 Timing from micro-seconds through hours Operates in both astable and mono- stable modes Adjustable duty cycle Output can source or sink 200mA Output and supply TTL compatible Temperature stability better than 0.005% per C Normally on and normally off output In DIE form, this device is an excellent selection for many chip and wire HYBRID CIRCUITS PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE The USM LM555 is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resettin desired. 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 duty cycle are accurately controlled with two external resistors and one capacitor.The circuit may retriggered and reset on falling waveforms, and the output circuit can source or sink up to 200mA or drive TTL circuits.
