Note that the lateral PNP structure has a Veb breakdown voltage of at least 700V so its not. The BC557 transistor functions like a switch and triggers ON/OFF in response to the conduction of the BC547 stage. It does this by shunting away base current from the NPN when Vce drops below a volt or so. BC557 is a PNP transistor hence the collector and emitter will be closed (Forward biased) when the base pin is held at. When there’s logic one, the clock input gets stopped, and the counter does nothing when the pulse arrives. The lateral PNP transistor structure prevents saturation and results in less Vce (sat) on the device compared to a typical multi-diode Baker clamp configuration. Its HFE ratings are 125 to 800, which makes it an ideal transistor to use as a small signal amplifier in electronic circuits such as audio signal. It is a general purpose PNP transistor that can be used as a switch or amplifier in electronic circuits. Pin 13 is for the clock, when there’s logic zero, the clock gets enabled and the counter increases one count for every clock pulse.

The BC557 is a widely used PNP bipolar junction transistor manufactured in small TO-92 package. Pin 16 is for the applied voltage from 3V to 15V, while pin 8 is for the ground. Note: Complete Technical Details can be found at the BC547 datasheet given at the end of this page. CD4017 is a CMOS decade divider or counter, having 10 output pins, from pin 1 to pin 7 and pin 9 to pin 11. Continuous Collector current (I C) is 100mA. But, what if you as a beginner try to control the bulb or light in your room? Sounds good? So, let’s start making the circuit.īut, before starting let’s understand the pin configuration of IC 4017. It is composed of semiconductor material usually with at. Remote controls are the household electronic devices used for television, air conditioning, etc. Abstract: C558 C557B c557a Philips C558 C556B c558 PNP transistors BC 557C bc557 and application BC557. BC557 is a semiconductor device used to amplify or switch electronic signals and electrical power. Hence, in this article, we are making a Remote Control Switch Circuit Using 4017 IC. That’s why we always try to come up with circuits that may develop the interest of a beginner. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.Experimenting with electronics by making simple projects but with little innovation is fun.
