The view and element placement of the popular chip 7400. The chip contains four logical elements AND-NOT (NAND). The two additional contacts supply power (+5 V) and connect the ground.
The former Soviet Union manufactured the analog K155ЛA3, where even contacts were placed identically (the voltage supply was also + 5 V, so at least in some cases the chips were replaceable). It was a very popular chip, widely used by amateurs.
