The method of selecting and non-gate chips can be considered from the following aspects:
First, the required input and output level characteristics need to be determined to ensure that the non-gate chip can meet the needs of the system.
Secondly, the speed and power consumption characteristics of the non-gate chip need to be considered to ensure its performance in the system.
In addition, the packaging and pin layout of the non-gate chip need to be considered to ensure that it can be easily connected to other circuit elements.
Finally, it is also necessary to consider the reliability and availability of non-gate chips to ensure their stability and availability in long-term use and maintenance.
2 Input four and gate chip 74LS08, 7432 or gate, 74LS14 not gate. When this picture is drawn with protel, it can be found from the library, I do not remember clearly, it seems that there are CD400X series is or not, and not, and all kinds of, more simulation, I remember.
