With the circuit shown, you build the monoflop with the C-MOS 4098, which contains two monostable multivibrators.

Once you press the pushbutton switch, the LED lights up and goes out after about half a second. This behavior corresponds to the transistor circuit of the Experiment 7.
|
The switching time T, in which the LED lights up, is determined by the capacitor C1 and resistor R2. In the data sheet of the C-MOS 4098 you find the formula... T = R2C1 × 0.5 The Monoflop responds directly to the pushbutton switch. It is triggered by a rising edge, as you can see in the illustration to the right. You can use the monoflop of the C-MOS 4098 also in a different way... |
