Using the 74HC in this way is not recommended. If you look at the data sheet, it says that the maximum logic level on the inputs should not be higher than Vcc. So, if you set Vcc to 3. However, the 74LVT is designed for the purpose of buffering between two circuits of differing voltages. That is, with the 74LVT, you can set Vcc to 3.

How to use 74hc245 buffer as voltage Level Shifter?

April 2, By Genius Devils 1 Comment. It is used to convert voltage level of different databus in embedded systems.

In this case ethernet controller ENC28J60 is 3. We have to convert voltage level. VCC we can apply It depends on how much volt we want on data pins. DIR and OE bar defins direction of data pins.

If you want to connect 3. So we will get 3.

In future I will post 74HC proteus demo tutorial. Keep visiting Genius Devils. Also dont forget to check our proteus designs tutorials. November 19, at 1: Return to top of page.
