One more circuit, stand alone PROM, EPROM copier with blank check and compare facility. In this circuit I am using a 12 bit address generator IC 4040 with 74245 8 bit transceiver IC but used as uni direction only. You can use any 8 bit unidirectional control latch like eg. 74373 etc. To compare the data i am using 74688. Now you can use your concepts for increasing the address bit, getting the output lateched etc.
Basic concept of over voltage indicator with cut off circuit. Hello friends long time have passed shared some circuit. Just let me know do you enjoy building small circuits and do you love simple and conceptional designs. We love innovative people with innovative ideas and help quickly and efficiently visualize their ideas into new product. We know time is money. So if YOU have an innovative idea to get it designed, call me to setup a time or if you have any other related query. My WhatsApp / Mobile No is +91 9831092629.
