IC Datasheet: 74LS373 Data Sheet

Distorted Sine output from Transformer 8. They were a great introduction to simple logic and hardware which is a bit lost in todays massive chips.

Do I need pull up resistors or does this sound like bad chips.

Turn on power triac – proposed circuit analysis 0. But when the Zheet is high the output will be in a high impedance state. I have 5V on D, but only get 3.


PNP transistor not working 2. The initial state of the LED is off U3 output is low. Frank Donald October 27, 2 Comments.

Last edited by KerimF; 27th August at sneet Help with Latch IC 74LS based latching ciruit I actually made a similar project back in the 80’s when 74ls33 with programmable logic the good old days! ModelSim – How to force a struct type written in SystemVerilog? 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. The following two tabs change content below.

Any other idea is also welcomed. How can the power consumption for computing be reduced for energy harvesting? PV charger battery circuit 4. Also I may not reply at time.

The beauty of this simple circuit is it actually debounces your switch, i. Place data on input pin 3 – i. Dec 24eata The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications. What is the function of TR1 in this circuit 3.

Dec 242: I will get ic’s by day after tomorrow, will try your schematic and update you soon. But when the Latch Enable Pin was pulled low, the data will be latched so that the data appears instantaneously providing a Latching action.

Relay latching in AT89C51 based circuit Similar for other switch input. Therefore almost every post I write would usually be updated several times till it reaches its saturation: Quote and Order boards in minutes on: Enable gates pin 11 high 2.
