MannyMax Posted May 15, 2004 Report Share Posted May 15, 2004 Hello everyone,I'm building the LED Digital Voltmeter project. The problem is that I need to have it drive a multiplexed display (the one I have is the 4-digit, common-anode Fairchild MSQ6411C).I was thinking of routing the 7107's outputs for each digit to one of 4 74245 ICs, then switching each 74245 out of high impedance mode when that digit is to be turned on. MOSFETs would be used to control each of the common anodes. I don't know if this will work at all, but it's a thought.Any help provided is greatly appreciated.
