In this circuit, we show how to avoid display leading zeros. Cuts Zeros Circuit is his name. We use the normal way 74HC393 as counter numbers. What we focus on is the 7447 extra functionality: L T , RBI, RBO. L T is a LAMP TEST input. when at logic level 0, every output is active so you can check if a segment or an output is broken or is used to verify that none of the segments are melted. RBI is RIPPLE BLANKING INPUT is used in multi-digit display and should be connected to the RBO of the previous digit (the digit to the left). In this way, you may avoid showing trailing 0 if not needed as you do in manual number writing. • Proteus File:https://www.dropbox.com/s/0035vzcj8uz... • Schema:https://www.dropbox.com/s/irj3nb0i2fh... • WebPage: http://jungletronics.blogspot.com.br/...
