IC pins are numbered anti-clockwise around the IC starting near the notch or dot.
read the datasheet or databook entry for the chip. there is no other reliable way.

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.
8-pin 555 timer IC
a tab on a metal case or a dot on a molded plastic case is typical.
It is a personal number used to identify a bank account, and is to be kept extremely secret. Most IC will have a dot or a mark or a tag TO IDENTIFY the pin 1 from the top pin 2 will be considered to be on your right sequentially clockwise
Simple case: First pin to the LEFT of a dot and/or a notch is pin 1. Chip with > 1 dot: The darker/deeper dot is the main dot, first pin to the left is pin 1. No dot or notch, just a semi circle on 1 side: First pin on the left is pin 1.
To identify pin connections on an AND gate IC chip, refer to the datasheet provided by the manufacturer. The datasheet will have a pinout diagram showing the location and function of each pin on the chip. Additionally, you can use a multimeter to test for continuity between pins to confirm their connections.

The 8085 is a 40 pin ic because Intel designed it that way.
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................
IC 7402 is different from the other type of IC like 7404,7408,7432 and 7400 when it is connected to have an output desired... if you noticed all i mentioned ic is connected from left to the right. input pin 1 and 2, output pin 3 input pin 4 and 5, output pin 6 input pin 13 and 12, output pin 11 input pin 10 and 9, output pin 8 while in nor gate, to have the desired output it must be connected from right to left... input pin 2 and 3, output pin 1 input pin 5 and 6, output pin 4 input pin 8 and 9, output pin 10 input pin 11 and 12, output pin 13
