Being not a machine, I always do silly mistakes or miss important things. You have LE fixed High, hence output equals input ModelSim – How to force a struct type 74s373 in SystemVerilog? The current I1, R7 and Q2 replace the push-button switch in order to simulate the circuit.
The beauty of this simple circuit kf it actually debounces your switch, i. Compare latch based and register based design 5. Equating complex number interms of the other 6. It doesnt latch in HIGH state.
74LS Datasheet(PDF) – TI store
PNP transistor not working 2. Relay latching in AT89C51 based circuit AF modulator in Transmitter what is the A?
Problem with 74LS latching! Our main server could be out of service anytime.
Need to either set LE low to latch the input or choose different latch. PV charger battery circuit 4. Dec 248: Digital multimeter appears to have measured voltages lower than expected. 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! Choosing IC with EN signal 2. What is the function of TR1 in this circuit 3.
The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems 74ld373.
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. Also I may not reply at time.
I have 5V on D, but only get 3. If you like I will draw the schematic for you. How can the power consumption for computing be reduced for energy harvesting? The following two tabs change content below. But when the OE is high the output will be in a high impedance state. Datq you have CD, the remaining 2 gates can be used to combine the 2 switches in one. Results 1 od 20 of The initial state of the LED is off U3 output is low.
IC Datasheet: 74LS373 Data Sheet
Thanks also for reminder on LED driver, I had dropped down to logic states! 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.
I will get ic’s by dzta after tomorrow, will try your schematic and update you soon. Part and Inventory Search.
