What is function of UM66?
what is the function of ic UM66.plz tel me
What is the working and principle of IC UM66?
ic um66 is a melody generator with 3 terminals (1-o/p, 2-vcc,3-grnd)
What is the working and principle of IC-UM66?
The UM66 is an electronic doorbell. It requires a button for the door, a single transistor, a battery and a speaker.
What is the voltage gain of the 2n2222 amplifier?
A: The gain of a transistor is not linear and even that varies from component to component. The gain can vary greatly depending on the Ic current and the load. Manufactures only give out a typical gain for a particular current. As a rule the lower the Ic current the higher the gain. To really find out what a particular transistor characteristics are a tektronik curve tracer is used.
Can you use ic 7485 as 8bit comparator?
use two of them for 8 bits.

What is UM66?
A UM66 is an IC or integrated circuit that generates a pleasing music sound. It works on a supply voltage of 3 volts.
What is application of ic um66?
It will generate a music signal by taking a less voltage at its input side.we can use it in our commercial applications
Is there any similarity between UM66 ic and BT66T 19L?
no there is no similarity. they both use for same purpose to produce melody tone in alarm
Why it is called um66?
um66 is a melody generator cmos ic it is a three terminal ic pin no: 1 is set to ground, and pin 2 is Vdd pin 3 is the output melody signal this ic generally operates from 1.5 to 5 volts it is generally used in toys, bells etc................
Why do you need to cascade ic in an amplier?
Because , it will be easier to use , remove & replace a cascaded ic .
What is the equivalent component to use in the place of IC 555?
Only a 555 can replace a 555, there is no equivalent. 555s are made by many companies, each with their own prefixes and suffixes, but all are 555s.
What is the working of HLS5T03 IC in musical burglar alarm?
This circuit generates a sweet melody for two minutes when it detects the shadow of a moving person. It uses the ROM IC UM66 to produce the melody. The music stops automatically. LDR is used as the light sensor. In day light, its resistance is low and conducts. This keeps the base of T1 high and it remains off. When the shadow of the moving person falls on the LDR, its resistance increases and the current flowing through it decrease. T1 then conducts and C1 charges. This provides power to IC UM66. Zener diode ZD is used to regulate the supply voltage to UM66 to 3 volts. When UM 66 gets 3 volts supply, it oscillates and the music tone from it will be amplified by T2 which can be heard through the speaker
