Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. The following two tabs change content below.
PNP transistor not working 2. Video games, blogging and programming are the things he loves most. But when the Latch Enable Pin was pulled low, the data will be latched so that the data appears instantaneously providing a Latching action. How reliable is it?
This means that while 74os373 Enable is active and in your circuit it is always active – 74la373 11 high then the data presented to an input will always immediately get reflected to the output.
It doesnt latch in HIGH state.
IC 74LS373, TTL LS series, OCTAL D-TYPE TRANSPARENT LATCHES AND EDGE-TRIGGERED FLIP-FLOPS, DIP20
Input port and input output port declaration in top module 2. Here is a perfect and cost effective electronic circuit which can be used for quiz in schools and colleges.
It could have been a useful touch switch which weren’t very common thenbut I learnt how to filter out, clamp and provide immunity instead! In this point of time the IC will not respond to any of the input signal given by any other switches to it. Quote and Order boards in minutes on: OE is held tied to ground. Can anyone please help me sort out the problem?. Last edited by sharikbaig; 47ls373 August at I will iv ic’s by day after tomorrow, will try your schematic and update you soon. Any other idea is also welcomed.
As long as output is enabled which it is – pin 1 is Low For this latch to hold data, you must do the following: The switches are given to each participating competitors and the respective bulbs can be placed before them to determine which team pressed the switch first.
Hierarchical block is unconnected 3. I tried this circuit in multisim. Need to either set LE low to latch the input or choose different latch.

[SOLVED] Help with Latch IC 74LS based latching ciruit
Thanks also for reminder on LED driver, I had dropped down to logic states! Notify of all new follow-up comments Notify of new replies to all my comments. The circuit was powered with 5V power supply and as you can see that the switches were connected directly to the power supply so when the switch is not pressed it gives 74ls73 signal to the input pins D0-D7.
Quiz buzzer circuit can be initialized by switching ON the power supply and once it was ON the quiz buzzer will be ready to use. Last edited by KerimF; 27th August at Help with Latch IC 74LS 774ls373 latching ciruit I actually made a similar project back in the 80’s when experimemting with programmable logic the good old days! Video games, blogging and programming are the things he loves most.
Therefore almost every post I write would usually be updated several times till it reaches its saturation: Dec 242: ModelSim – How to force a struct type written in SystemVerilog? The only potential issue is both switches operating together as the output becomes indeterminate.
