I am building a GIANT spectrum analyzer for our churchs VBS program. I am using an array of solid state relays driving 120 VAC lights and am tapping into a small commercial spectrum analyzer to control the relays. Problem is that the unit I am using multiplexes its array of LEDs (rows and columns) so that each is on for only a small time period. Unfortunately, the solid state relays pick up on this and the 120 VAC are dim and flashing noticeably. If I add a 22 uf cap directly to the the output of the driving logic (74VHC595) to hold the voltage through the off cycle, the 120 VAC light works great. Does this sound OK or could this modification damage the 74VHC595 over time? (dont know if the current required to charge or discharge the cap might be exceeding the ICs capability). Thanks for any help.
