By connecting the ends of a 10K trimmer potentiometer to the two pins( 1 and 8 of an 8 pin dip OP Amp) and the slider to -supply rail it is possible to null the output to exactly 0 volts. This might be important in a DC coupled amp like a servo driver. Otherwise these pins can be left open.
1st and 5th pins.
The LM741 pins depends on the particular package selected. The most common arrangement is... 1.) Offset Null 2.) Inverting Input 3.) Non-Inverting Input 4.) Supply Voltage Minus 5.) Offset Null 6.) Output 7.) Supply Voltage Plus 8.) No Connection This is true for both the 8 pin metal can and the 8 pin DIP. Typical connection is to connect a 10K potentiometer between the two offset nulls with the wiper connected to Supply Voltage Minus.
for simplicity of calculation of no of pins
these two pins are biasing pins of ICs.
it have 40 pins 1st one is ground and last one is Vcc. Itplh = 450
power supplies +5v and -5v will be given to 7 and 4 pins respectively,therefore it is used for giving power suppply to ic 741

The CA3130 op amp has the following pinouts: 1 Offset null 2 Inv. input 3 Non-inv. input 4 V- and case 5 Offset null 6 Output 7 V+ 8 Strobe Use the link below to review a data sheet where you'll find more information than you can possibly use.

The 555 has 8 pins...GroundTriggerOutputResetControlThresholdDischargeVcc
40 PINS
The 7805 regulator IC has three pins; input, output, and ground. The case is also a pin, but it is grounded, so there are still only three pins, for all practical purposes.
IC pins are numbered anti-clockwise around the IC starting near the notch or dot.
these two pins are biasing pins of ICs.
Time calculation metods of ic 4060 at different pins
The non-inverting pins of the LM393 are 3 and 5.
to avoid floating pins ...........so as to avoid rail to rail current
It is an opamp chip consisting of 8 pins
