monolithic circuit is a highly stable device as producing accurate time delay or timing pulse. Additional terminals are provided for triggering or reseting, if desired. In the time delay or monostable mode of operation, the time is precisely controlled by one external Resistor
In the astable mode of operation, the frequency and duty cycle are accurately and independently controlled with two external Resistors
and one Capacitor
The uiiuil of llie TA7555P
may be triggered dud reset on falling wavoforms, and the output structur? can source and sink up to 200MA
or drive TTL circuit. Operation is specified for supplies of 5 to 15V.
