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.

20 and 40 feet container have markin ic 80 what is the meaning of this marking?
Intercontainer or ic number shows that container is approved by international union of railways, ic no shows that which railway organization has certified that container
Why to have even number of pins in ic?
to avoid floating pins ...........so as to avoid rail to rail current
A soup can has diameter 6.6 cm The label on the can ic 8.8 cm high There is a 1-cm overlap on the label what is the area of the label?
Diameter = 6.6cm, so radius = 3.3cm Circumference = 2 * pi * radius Circle. = 20.735 cm Now we multiply by the length..... 20.735 * 8.8 = 182.468 cm^2 Now we have the 1cm overlap, which technically is a rectangle of dimensions 1cm * 8.8cm i.e. 1 * 8.8cm = 8.8 cm^2 We just add this on..... 182.468 + 8.8 = 191.268 cm^2 or 191.27 cm^2 (to 2dp)
What is masking in VLSI?
'Mask' simply is an arrangement of opaque & transparent areas, that is used to bear a 'pattern' in VLSI 'Patterning' process. As we know, an IC is a combination of various 'layers' of silicon, each having a certain function in the big picture. Now in Patterning process, a bare silicon wafer is selectively exposed by patterning the insulating coating (silicon dioxide) on top. To pattern the SiO2, we use an 'organic photo-resist' layer, on top of SiO2. The 'mask' contain the design we want, where we want to expose Silicon. So, first we place the mask & pattern the resist (through UV/X-ray, Organic acid, etc etc) and then we pattern the SiO2 that has been exposed now. Resist will be completely removed later. There are positive & negative Masks also, considering the opaque & transparent regions.
How do you identify pin connections and an AND gate IC chip?
read the datasheet or databook entry for the chip. there is no other reliable way.
How do you identify pin 1 on an IC?
IC pins are numbered anti-clockwise around the IC starting near the notch or dot.
Why first pin of ic 7806 is used as input?
Because that is the way the chip was designed. No special reason.
How do you identify pin no 1 of an ic?
a tab on a metal case or a dot on a molded plastic case is typical.
Electronics Pin Number?
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
How do you identify pin connections on AND gate IC chips?
you start from the notch of the I.C and then you go anti clockwise making the pin at the bottom of the notch 1 and the pin above the notch 14 .
What is a IC holder used for?
For an IC chip
How to identify IC legs numbers?
We might identify an integrated circuit (IC) by recognizing it in a circuit. A voltage regulator in a piece of electronic equipment might be an example of an IC that a technician might recognize. There is also the idea that the number on the package can be used to cross reference the device and identify it. There are a number of cross reference guides on the web that will assist in locating a data sheet on a particular package.
Is there any special IC for amplitude modulation?
MC1496-AM modulator and demodulator chip -- shark
Why 8085 is a 40 pin ic?
The 8085 is a 40 pin ic because Intel designed it that way.
How do reset Samsung 4200 Chip?
Buy or Build your own resseter, the chip has a 24c04 eeprom, you only need 4 pins to program it trough the serial DB9 port of your pc. Software: Ic-prog or similar
When was the IC Chip invented?
1958
