IC Logic Gate 74LS04N NOT
The 74LS04 is a hex inverter IC consisting of six independent NOT gates, each with one input and one output. It inverts the logic level of the input signal — converting a HIGH to LOW and vice versa. NOT gates are fundamental digital logic gates commonly used in various digital applications. These inverters are built using NMOS and PMOS transistors and are simple in design.
