The HEF4047BT-Q100J is a logic integrated circuit from NXP Semiconductor of the HEF4047 family. It is a Monostable/Astable Multivibrator for usage in different applications. The device features two outputs (Q and !Q), with a positive-edge triggered monostable and a negative-edge triggered astable. By using this device we can generate timing signals and create a variety of widely used bistable circuits.

The application field of the HEF4047BT-Q100J is, first and foremost, as a Monostable/Astable Multivibrator, in which it is typically used to generate timing signals and control circuits. The monostable operation refers to a single pulse generator, which produces a single output pulse when triggered by an input signal. The astable operation means that the device produces a continuous output pulse train with a period determined by the constants connected to the device. The device may also be used in various flip-flop and memory circuits due to its built-in reset feature.

The two applications of the HEF4047BT-Q100J can be further explained by looking at its internal working principles. In the monostable operation, a single positive edge triggered pulse is generated when an input trigger pulse is applied. The output pulse width is determined by the external RC network connecting to the device. The device is a positive edge triggered circuit and will not respond to negative edges. On the other hand, the astable operation is a continuous operation where the device generates an output pulse train at a certain frequency. The period of the output pulse train is determined by the external resistor and capacitor connected to the device. The device will reset when the low going M reset is triggered.

In conclusion, the HEF4047BT-Q100J is a logic integrated circuit from NXP Semiconductor of the HEF4047 family. It is a Monostable/Astable Multivibrator which can be used to generate timing signals and create various widely used bistable circuits. Its applications include monostable operation and astable operation, with its working principle involving an external RC network and reset circuit. With its simple setup and use, it is a great device for various projects and circuits.
