When testing the response of many pulse-width-modulated (PWM) systems, there's a need to independently vary a multivibrator's frequency and duty cycle. Such systems include dc motors, ultrasonic ...
The MM54C221/MM74C221 is a dual CMOS monostable multivibrator. Each one-shot has three inputs (A, B and CLR) and two outputs (Q and Q ). The output pulse width is set by an external RC network. The A ...
