NE555
Features - Timing from microseconds to hours - Astable or monostable operation - Adjustable duty cycle - TTL-patible output can sink or source up to 200m A - On products pliant to MIL-PRF-38535, all parameters are tested unless otherwise noted. On all other products, production processing does not necessarily include testing of all parameters. 2 Applications - Pulse-shaping circuits - Missing-pulse detectors - Pulse-width modulators - Pulse-position modulators - Sequential timers - Pulse generators - Frequency dividers - Industrial controls CONT 6 THRES 5 ÎÎÎÎ RESET 4 ÎÎÎ R1 1ÎÎÎ ÎÎÎ 3 OUT 2 TRIG ÎÎÎ 1 GND Simplified Schematic 7 DISCH 3 Description The Nx555 and Sx555 devices are precision timing circuits capable of producing accurate time delays or oscillation. In time-delay or monostable operating modes, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle are...
