Place data on input pin 3 – i. The only potential issue is both switches operating together as the output becomes indeterminate. As we all know the operation of flip flop that any input to the D pin at the present state will be dataa as output in next clock cycle.

If you like I will draw the schematic for you. ModelSim – How to force a struct type written in SystemVerilog? Input port and input output port declaration shee top module 2. When the OE pin is low input data will appear in the output.

You people are very helpful, Thanks. Each momentary switch would latch a solenoid valve and when activated switch off the others valvesa bit like a manual washing machine.

Quote and Order boards in minutes on: CMOS Technology file 1. Dec 242: But when the OE is high the output will be in a high impedance state. The time now is Compare latch based and register based design 5.

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! Latest posts by Frank Donald see all.

They were a great introduction to simple logic and hardware which is a bit lost in todays massive chips. Here is an example http: Our main server could be out of service anytime.

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. Need to either set LE low to latch the input or choose different latch.

You have LE fixed High, hence output equals input Frank Donald October 27, 2 Comments. As long as output is enabled which it is – pin 1 is Low For this latch to hold data, you must do the following: Digital multimeter appears to have measured voltages lower than 74ls337.

Do I need pull up resistors or does this sound like bad chips. Last edited by KerimF; 27th August at These small chips were 18 or 24 pins? Part and Inventory Search. 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! The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications. The beauty of this simple circuit is it actually debounces your switch, i.
