musical 3 pin IC UM66 and a popularly known Transistor BC548b
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................
7404
Is it APR 9600 or ARP 9600? If it is APR 9600 sound record/replay IC, check out the link given below. It contains the pin configuration of the IC.
For what design go to datasheetlocator.com and look oit up
You can just Google the IC number and check the datasheet. This is very useful for getting the pin configuration of other IC as well. Anyway 7486 is a 14pins, 4 independence gates of XOR Gate Input Output #1 Pin1 Pin2 PIN3 #2 Pin4 Pin5 PIN6 #3 Pin10Pin9 Pin8 #4 Pin13Pin12 Pin11 Others Vcc Pin 14 Gnd Pin 7 Hope that helps.
The 8085 is a 40 pin ic because Intel designed it that way.
IC's which starts from 7 are most of them are digital ic's . not all the IC's starts with 7 for example LM380 audio IC CTC810 audio amplifier ic and lm317 voltage regulator ic ,NE555 timer ic, 4017 counter and so other. there are no fact behind them . 7400- nand 7402 -nor 7404-not 7408-and 7432-or 7486-exor 74266-ex-nor 74147 priority encoder.
It is a a timer of very stable timing if everything else is stable. It widely use for that reason it is ab 8 pin dual in line pin configuration, The design is widely available from manufactures and Internet pages.
What enable1&enable2 in pin l293d
40
Collector emittor and control I believe. The configuration depends on the IC though.
on facing the side having black cover ie the front side...starting from the left.. pin1:supply pin2:ground pin3:output
IC pins are numbered anti-clockwise around the IC starting near the notch or dot.
