74LS30 – 8 Input NAND Logic Gate IC – Datasheet

The 74LS30 IC package contains two independent positive logic 8-input NAND Gates. It is the part of 74XXYY IC series. The 74LS30 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC 74LS30 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.

What is a NAND Gate?

A NAND Gate is a logical gate which is a combination of AND and NOT gates. It is considered as a “universal” gate in Boolean algebra as it is capable of producing all other logic gates. A NAND gate consists of one or more inputs with a single output. The output of the NAND gate is always at logic 1 and only goes to logic 0 when all the inputs to the NAND gate are at logic 1. In other words, the output of the NAND gate always remains true if at least one of its inputs remains false.
