Some of the text within the PDF file :
It is compatible with standard TTL (Transistor-Transistor Logic).
The 74LS04 is a widely used hex inverter integrated circuit (IC). It is part of the 74LSxx series, which encompasses a range of logic gates and flip-flops. In particular, the 7404 consists of six independent inverters, each of which can take an input signal and produce its logical complement at the output.
The "74" in the name refers to the series of integrated circuits introduced by Texas Instruments, and the "LS" signifies the low-power Schottky technology used in its construction. The "04" indicates that it is a hex inverter.
The 74LS04 is available in various package types, such as DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit). It has a total of 14 pins, with each inverter having its input (labeled A) and output (labeled Y).
