Logic-Multivibrators are a type of electronic circuits that use two transistorized devices, electronic amplifiers, or op-amps as a switching element. These circuits serve as digital timers, pulseenlargers, frequency dividers, as well as comparators in electronic systems.The MC14528BDR2G is a dual monostable multivibrator. It is wall manufactured by ON Semiconductor and is available in an SO package. The MC14528BDR2G can be used to divide a single input signal frequency into two unequal frequencies and produce two output signals.The MC14528BDR2G is a remarkably powerful device designed to provide clean, delayed pulses. It is designed to trigger on a single input signal and can be used to generate a single pulse of adjustable duration on either of its two outputs. Its operation is quiescent and it typically draws less than 1 Microamp current when idle.The basic circuit and diagram of functioning of MC14528BDR2G is shown above. The two transistors connected to control the logic output points are connected to respective inputs for updating logic outputs.The input pulse is basically between two terminals A and B. It enables the low-level output when it is at a threshold level and high-level output when it goes below the threshold level. Hence the input pulse is properly terminated at the output and the duration of the output pulse will be adjusted by the capacitor and resistor values at the input.Since the output is high when the input is low and vice versa, the output pulse is delayed with respect to the input pulse.In addition to this, the MC14528BDR2G has a special feature that can adjust the duration of the pulses. The adjustable pulses can be output by using a timing circuit C and R connected to the control input C1 of the device.The MC14528BDR2G has a number of different applications. One of its most common uses is to provide noise isolation in audio systems. It can be used to delay the action of any switch which may be feeding multiple applications. It can also be used to serve as a clock divider and has also been used in voltage delay circuits.It is essential to note that this dual monostable multivibrator is an ideal device for interface purposes, such as controlling noise. It provides exceptional low-level noise immunity and its low power consumption results in very low total power dissipation.
