The 74L04 is a 14-pin integrated circuit (IC) chip. It is an integrated circuit in the 74xx series which contains six NOT gates. The NOT gates are a type of electronic circuit that reverses the input signal. The inputs of the NOT gates are logic levels of either 0 or 1 and the outputs are the reverse of those inputs. The 74L04 is typically used in digital logic systems and can be used to create logic functions such as AND, OR, and NOR. It is fabricated with low-power Schottky transistors and is capable of operating over a wide range of voltage and temperature.
