MOTOROLA ANALOG IC DEVICE DATA
APPLICATIONS INFORMATION
Tone Burst Generator
For a tone burst generator, the first timer is used as a
monostable and determines the tone duration when triggered
by a positive pulse at Pin 6. The second timer is enabled by
the high output of the monostable. It is connected as an
astable and determines the frequency of the tone.
Dual Astable Multivibrator
This dual astable multivibrator provides versatility not
available with single timer circuits. The duty cycle can be
adjusted from 5% to 95%. The two outputs provide two phase
clock signals often required in digital systems. It can also be
inhibited by use of either reset terminal.
