TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA7555P,TA7555F
TIMER APPLICATIONS
The TA7555P 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 and capacitor.
In the astable mode of operation, the frequency and duty cycle are
accurately and independently controlled with two external
resistors and one capacitor.
The circuit of the TA7555P may be triggered and reset on falling
waveforms, and the output structure can source and sink up to
200mA or drive TTL circuit.
Operation is specified for supplies of 5 to 15V
FEATURES
l Timing from microseconds through hours
l Operates in both astable and monostable modes
l Adjustable duty cycle
l Output can source or sink 200mA
l Output TTL compatible
l Temperature stability of 0.005% / °C (Typ.)
l Normally ON or normally OFF output
l Direct replacement for SE555 / NE555
Weight P-DIP8-300-2.54 : 0.5g (Typ.)
