I am trying to create a manual demonstration circuit for a 74HC595 shift register. Se my circuit below. The problem I am having is that I am only getting a +0.7V signal to the data, clock, and latch pins of the 74HC595 when one of the buttons are pushed. The
S4 RESET switch works fine (normally high at 5V, press switch to bring down to 0V), however
S3 do not accomplish the reverse scenario (normally LOW, press switch for HIGH) correctly. You will note that I am also trying to debounce the switching with a capacity or resistor. I suspect this debouncing set up is creating my problem.
Does anybody have any advice on how to create a debounced normally LOW, momentarily HIGH switch that switches between 0V and 5V?
