Hi brother,I was working on 74151 Ic. I am switching the address of IC through STM32 microcontroller, like I have connected controller’s 3 I/O pins to IC’s address pins and through controller’ programming,I’m changing the address.but the problem is,along with switching,I am also getting some random data through the output pin of IC(00 in hex,i have connected output pin of IC to the USB-TTL Rx pin). So to remove this error, i have done a lot of things like pull up,pull down,but does not get any solution . So please if you can help out with this
Tell me what is use of enable input in ic no 74151
