LM741 operational amplifier is a high gain electronic voltage amplifier coupled with a DC. There is only one Lm741 op-Amp. The operational amplifier is used as a comparator and compares the two signals; the non-inverting and inverting the signal.
The main role of the IC is to carry out the mathematical operation in circuits. LM741 can operate with either a dual or single power supply voltage. Most op-amps have large gains and are used as voltage amplifiers.

LM741 pinout
LM741 has eight pins. The first and fifth pins are the offset and null pins used to balance the input voltage and remove the offset voltage. The second pin is the inverting signal input, while the third one is the non inverting signal input.
The fourth pin is the negative supply voltage, and the seventh is the positive supply voltage. The sixth pin of the IC is the output pin, and its eighth is the NC, which is not connected.
Look at the LM741 schematic pinout diagram above.
LM741 Equivalents and Replacement Details
The equivalents of LM741 are Lm 748, Mc 1439, Lm 201, Lm 709C, Lm741C, and LM741A. When the input source is connected to the inverting pin and the feedback to the output pin, the IC is said to be inverting.
