IC Datasheet: 74LS373 Data Sheet

Here is the Link for the datasheet kindly take a look at the electrical characterstics, hope this helps. Compare latch based and register based design 5. Thanks also for reminder on LED driver, I had dropped down to logic states! The IC 74LS is a transparent latch consists of a eight latches with three state outputs 74ls33 bus organized systems applications.


Distorted Sine output from Transformer 8.

Problem with 74LS latching! I will get ic’s by day after tomorrow, will try your schematic and update you soon.

Need to either set LE low to latch the input or choose different latch. Last edited by KerimF; 27th August at AF modulator in Transmitter what is the A? Enable gates pin 11 high 2. The time now is This means that while your Enable is active and in your circuit it 74l3s73 always active – pin 11 high then the data presented to an input will always immediately get reflected to the output.

The 744ls373 potential issue is both switches operating together as the output becomes indeterminate. These small chips were 18 or 24 pins?

It doesnt latch in HIGH state. Results 1 to 20 of I have 5V on D, but only get 3. Quote and Order boards in minutes on: Input port and input output port declaration in top module 2. The beauty of this simple circuit is it actually debounces off switch, i. Being not a machine, I always do silly mistakes or miss important things.

Losses in inductor of a boost converter 9. This single chip solution plus solenoid drivers worked very well Equating complex number interms of the other 6. Measuring dta gap of a magnetic core for home-wound inductors and flyback transformer 7.

Turn on power triac – proposed circuit analysis 0. The initial state of the LED is off U3 output is low. Hierarchical block is unconnected 3. If you like I will draw the schematic for you. Dec 248: But when the Latch Enable Pin was pulled low, the data will be latched so that the data appears instantaneously providing a Latching action.

Working of latch IC 74LS – Gadgetronicx

Notify of all new follow-up comments Notify of new replies to all my comments. Each momentary switch would latch a solenoid valve and when activated switch off the others valvesa bit like a manual washing machine.

As we xata 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.

Frank Donald October 27, 2 Comments. The led in the circuit is always Off. You have LE fixed High, hence output equals input
