Zulutaur It can not be used as a supply pin or input. The latest information is available on the Internet at URL http: This analysis confirms the suspicion that using a 74HC00 will not be safe. Datxsheet data sheets describing multiple type numbers, the highest-level product status determines the data sheet status. The product status of the device s described in this data sheet may have changed since this data sheet was published.

Figure 1. Let me tell addition. Imagine the block switch A. Or connect it to Vcc. Then, the switch turns ON or closed circuit. The electrical current can flow both ways.
Or connect it to GND. Then, It gets the opened circuit. The current cannot flow like the normal switches The general features We can use easily. They are the same shape, DIP But pinouts are different. I like it because… Wide voltage supply—The maximum supply Vcc at pin 14 must not exceed 18V. Low resistance—when switched ON has 50 ohms only. And you can read more detail below. Pin and Function Compatible with B.
They may be good ideas for you. Signal bus controller circuit using This is a data bus controller circuit. We connect all the control pins together. To control all ports data. The signal can come in or out. In another hand, the signal cannot flow when control pins are low status.
Is it easy? Yes, It is so easy. Adding digital voltage control Suppose that we want to change the adjusting voltage. To be digital control with any logic signal. For example the Arduino or others. Digital logic controls voltage 3V, 6V , 9V, and 12V.
It is like the above circuit. Also, It is easy with helping of 74HC analog switches. If you are interested in this idea. You may use external power supply 5V for this IC. I believe in you can do it. Sharing is caring!
