Can anyone please help me sort out the problem?.

I have 5V on D, but only get 3. Problem with 74LS latching!

IC Datasheet: 74LS373 Data Sheet

Last edited by KerimF; 27th August at Heat sinks, Part 2: Therefore datwsheet every post I write would usually be updated several times till it reaches its saturation: The initial state of the LED is off U3 output is low. You people are very helpful, Thanks. OE is held tied to ground.

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 IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications.

74LS373 – Octal Transparent Latch 3 State

Place data on input pin 3 – i. This means that while your Enable is active and in your circuit it is always active – pin 11 high then the data presented to an input will always immediately get reflected to the output.


But when the Latch Enable Pin was pulled low, the data will datashwet latched so that the data appears instantaneously providing a Latching action. As we all know the operation of flip flop that any input to the D pin at the present state will be given as output in next clock cycle. Here is an example http: CMOS Technology file 1. Our main server could be out of service anytime. Frank Donald October 27, 2 Comments.

This IC operates with maximum of 5 V and widely used in many kinds of electronic appliances. Dec 242: The time now is Any other idea is also welcomed. Here is the Link for the datasheet kindly take a look at the electrical characterstics, hope this xatasheet.

If you like I will draw the schematic for you. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.

Quote and Order boards in minutes on: Losses in inductor of a boost converter 9. What is the function of TR1 in this circuit 3. You have LE fixed High, hence output equals input Datasheet of 74LS is also attached. Thanks also for reminder on LED driver, I had dropped down 774ls373 logic states!

Results 1 to datqsheet of Part and Inventory Search. Also I may not reply at time.

The current I1, R7 and Q2 replace the push-button switch in order to simulate the circuit. The following two tabs change content below.


Working of latch IC 74LS – Gadgetronicx

The beauty of this simple circuit is it actually debounces your switch, i. Enable gates pin 11 high 2. Each momentary switch would latch a solenoid valve and when activated switch off the others valvesa bit like a manual washing machine.

Hierarchical 7l4s373 is unconnected 3. This single chip solution plus solenoid drivers worked very well How reliable is it? Last edited by sharikbaig; 27th August at Distorted Sine output from Transformer 8.

It doesnt latch in HIGH state. Choosing IC with EN signal 2. Need to either set LE low to latch the input or choose different latch.

Similar for other switch input. As long as output is enabled which it is – pin 1 is Low For this latch to hold data, you must do the following: Video games, blogging and programming are the things he loves most.

Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. 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!
