I assumed thats what its designed to be. See the datasheet on usage.
two You can verify this on the datasheet.

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................
read the datasheet or databook entry for the chip. there is no other reliable way.
Check the datasheet for pinout.
This depends on the IC. Visual inspection will only go so far. You will need to test it and compare the testing to the datasheet; if it is not testing as specified in the datasheet, then it is bad. Sorry, there's no one easy answer for all IC's.
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.
Type LM567 datasheet into Google, fool!

The 8085 is a 40 pin ic because Intel designed it that way.

What enable1&enable2 in pin l293d
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.
