Experiment With NAND Gate - CMOS 4011


(CMOS 4011 Layout)

Circuit


Try this super-simple experiment. The output frequency is about 1kHz (square wave).


The NAND output is on CH1 (bottom), CH2 (top) is the test signal 1kHz.

Hello! I have tried this about ten times, but the output of the first gate just stays up. Any hints what could be the problem?

Hi, maybe you missed out the 1st gate "enable" input? Try to make it HIGH.
