UM works in the range of volts, voltage higher than 5V can damage the IC, so datashret we are using it with other circuit or using a high voltage source, a Zener diode must be connected, to protect the IC.

Hi buddy there is basic flaw in circuit. As we have used 9v battery, so we have used Zener Diode 3.

Quote and Order boards in minutes on https: Zener Diode is just like the other diodes, with only one difference. As we have used 9v battery, so we have used Zener Diode 3.

There should be a resistence of 1K. With some basic mistakes datasbeet as in your circuit the beginners will get disheartened when there ckt doesn’t work.

U should be careful while drawing the circuit. This voltage is called Breakdown Voltage or Zener Knee voltage.

UM – Three Siren Sound Generator – PDIP-8

U should be careful while drawing the circuit. It is generally used in alarms and toys. It is a low cost and low powered 8 pin IC. UM Pin diagram and Pin description is given below, taken from its Datasheet:. All the diodes allow flow of current in only one direction forwardbut Zener diode can allow current in reverse direction if the voltage goes beyond a certain limit.

While building circuits many times we need to generate sounds like a musical sound or some kind of alerting sound.
