Problem:
CD4044 truth table says input S=0,R=0 yields Q=0 since R=0. However, upon power up, Q=1 and holds. How can we modify circuit to ensure Q=0 upon power up.]
Any ideas on how to force Q=0 upon power up? S=R=1 at start up now. Could we use an R-C on the R input to make R come from 0 at start up to 1? Then both R and S are 1. When S=0, R=1, Q=1 and when S=1, R=0, Q=0.
