What problem you are facing? If you like I will draw the schematic for you. This single chip solution plus solenoid drivers worked very well Enable gates 74ls73 11 high 2.
But when the Latch Enable Pin was pulled low, the data will be latched so that the data appears instantaneously providing a Latching action. AF modulator in Transmitter what is the A? Compare latch based and register based design 5.
Hierarchical block is unconnected 3. It could have been a useful touch 74,s373 which weren’t very common thenbut I learnt how to filter out, clamp and provide immunity instead! Datasheet of 74LS is also attached. Quote and Order boards in minutes on: Quiz buzzer circuits have been available numerous in number yet we face many problems in most of the circuits and some cost much.
[SOLVED] Help with Latch IC 74LS based latching ciruit
Here is the Link for the datasheet kindly take a look at the electrical characterstics, hope this 74ls73. Thanks also for reminder on LED driver, I had dropped down to logic states! Frank Donald October 27, 2 Comments.
How do you get an MCU design to market quickly? This low state in the LE pin enables the latch of the IC thereby providing continuous high signal in the output pin. Losses in inductor of a boost converter 9. The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications. Last edited by sharikbaig; 27th August at Here is a perfect and cost effective electronic circuit which can be used for quiz in schools and colleges.
Working of latch IC 74LS – Gadgetronicx
Similar for other switch input. 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. As we all know the operation of flip flop that any input to the D pin at the present state will be given as 74l373 in next clock cycle. How reliable is it? Results 1 to 20 of When the OE pin is low input data will appear in the output.
So this quiz 74lw373 circuit was cost effective and efficient comparing to other circuits. Last edited by KerimF; 27th August at 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.

Any other idea is also welcomed. You people are very helpful, Thanks.
IC 74LS373, TTL LS series, OCTAL D-TYPE TRANSPARENT LATCHES AND EDGE-TRIGGERED FLIP-FLOPS, DIP20
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 low signal to the input pins D0-D7. Video games, blogging and programming are the things he loves most.
