2011年5月4日 · Hi i need help. My teacher gave us a project to do and didnt tell us how. WE have to make a now serving display that when you toggle the switch it counts up 1. We have to use 2 seven seg displays a 74ls47n binary to decimal drive. I know i need to cascade the 74ls193 to make a eight bit counter...

2012年2月9日 · My goal is to use 74ls193 as counter and design BCD up and down counter from 00 - 99 vice versa (2 digits). I figured out how 74ls193 work as BCD counter, but the problem is, when it count down, from 9 - 0.. it doesn't come back to 9.. it stay at 0 all the time.

2014年11月6日 · The 74LS163 is a completely synchronous counter, that means all updates of the states occur when the clock CLK is activated. The circuit is a 4 bit counter, that means it has 2^4 = 16 states. Every state sj, is given by the fourtiple Q = (qd, qc, qb, qa), where qa is least significant, as is...

2010年12月20日 · Hi I need some help on building a traffic light circuit. Below I have drawn a schematic diagram and I am unsure if it's correct or not. I have builded this on a breadboard using three AND gates (74LS08), 1 OR GATE (74LS32P), a INVERTER (74LS14N) 555 timer chip and a counter chip (74LS193N).

2023年3月30日 · Hello everyone! I'm about to start a little project that has to be consist of hardware components only without using any programming language (can not include programmable devices/microcontroller). The project's purpose is to imagine a system that checks a car battery, one circuit needs to...
