TOPIC 2: MONOSTABLE MODE

test

YOURSELF

1. Determine the time period of a monostable 555 multivibrator.

2. A monostable multivibrator has R = 120kΩ and the time delay T= 1000ms,
calculate the value of C?

3. A Monostable 555 Timer is required to produce a time delay within a circuit. If
a 10uF timing capacitor is used, calculate the value of the resistor required to
produce a minimum output time delay of 500ms.

4. 555 Timer is connected in monostable multivibrator mode. What is the output
if no input trigger is given?

ANSWER:

1. Tw =1.1RC

2. 7.5µF
3. 45.5kΩ

4. Low
