cd4050 application
I am making a small test project for 8x8 dot matrix display using AT89S52 microcontroller and i am having some problems. Currently i am using only a single display (the project is on a breadboard(s) ). All went well, the message was scrolling fine on the display until i decided to use buffers to increase the brightness(the display was not bright enough). I used the CD4050B non inverting buffers, the problem is that when i give four or more inputs through the buffer the display suddenly goes blank after a second or so. I cant understand whats the problem. Can anyone please help me out ?
P.S I want to use buffers only to increase the brightness so please dont suggest transistors
