If you like I will draw the schematic for you. How do you get an MCU design to market quickly?

This IC operates with maximum of 5 V and widely used in many kinds of electronic appliances. When the OE pin is low input data will appear in the output.

Our main server could be out of service anytime. How reliable is it? Notify of all new follow-up comments Notify of new replies to all my comments. The following two oc change content below.

So this quiz buzzer circuit was cost effective and efficient comparing to other circuits. Do I need pull up resistors or does this sound like bad chips.

The following two tabs change content below. The initial state of the LED is off U3 output is low. 74,s373 also for reminder on LED driver, I had dropped down to logic states! Digital multimeter appears to have measured voltages lower than expected.

You people are very helpful, Thanks. Quiz buzzer lc can be initialized by switching ON the power supply and once it was ON the quiz buzzer will be ready to use. Help with Latch IC 74LS based latching ciruit I actually made a similar project back in the 80’s when experimemting with programmable logic the good old days! The only potential issue is both switches operating together as the output becomes indeterminate.


How can the power consumption for computing be reduced for energy harvesting? Need to either set LE low to latch the input or choose different latch. This single chip solution plus solenoid drivers worked very well Turn on power triac – proposed circuit analysis 0.

Here is the Link for the datasheet kindly take a look at the electrical characterstics, hope this helps. Iv in inductor of a boost converter 9. Projects LEDtransistors.

AF modulator in Transmitter what is the A? IC 74LS forms the main heart of this circuit and it was a transparent latch which consists of a eight latches with three state outputs.

Working of latch IC 74LS – Gadgetronicx

Part and Inventory Search. I mean 74s373 part of circuit is troubling you? OE is held tied to ground. The 774ls373 of this simple circuit is it actually debounces your switch, i. ModelSim – How to force a struct type written in SystemVerilog? 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.

The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications. It doesnt latch in HIGH state. PNP transistor not working 2. Latest posts by Frank Donald see all. Datasheet of 74LS is also attached. CMOS Technology file 1. In this point of time the IC will not respond to any of the input signal given by any other switches to it.


Video games, blogging and programming are the things he loves most.


Quote and Order boards in minutes on: Distorted Sine output from Transformer 8. I will get ic’s by day after tomorrow, will try your schematic and update you soon. Lets look into the working of this quiz 74ld373 circuit.

It 74le373 be a great mini project to do at you home and i bet you will like it. Results 1 to 20 of Being not a machine, I always do silly mistakes or miss important things.

Originally Posted by KerimF. As long as output is enabled which it is – pin 1 is Low For this latch to hold data, you 74ls733 do the following: I have 5V on D, but only get 3. Similar for other switch input. And the high output signal further switches the Jc on and thereby the respective bulb of the team will glow and also the transistor T1 connected to the Buzzer will switch the buzzer ON. Since the output was latched with the input this circuit eliminate the confusion among the participants and also it provides room for eight teams to play at a time.
