If you like I will draw the schematic for you. Dec 242: These small chips were 18 or 24 pins?

Datasheet of 74LS is also attached. How do you get an MCU design to market quickly?

Our main server could be out of service anytime. Heat sinks, Part 2: Dec 248: It doesnt latch in HIGH state.

The beauty of this simple circuit is it actually debounces your switch, i. Last edited by KerimF; 27th August at Here is an example http: CMOS Technology file 1.

Motorola – datasheet pdf

Video games, blogging and programming are the things he dayasheet most. Need to either set LE low to latch the input or choose different latch. Each momentary switch would latch a solenoid valve and when activated switch off the others valvesa bit like a manual 74lz373 machine. Input port and input output port declaration in top module 2.


Therefore almost every post I write would usually be updated several times till it reaches its saturation: Do I need pull up resistors or does this sound like bad chips. ModelSim – How to force a struct type written in SystemVerilog?

You have LE fixed High, hence output equals input Compare latch based and register based design 5.

74LS373 – Octal Transparent Latch 3 State

Fatasheet Posted by KerimF. Any other idea is also welcomed. Latest posts by Frank Donald see all. Enable gates pin 11 high 2. Synthesized tuning, Part 2: Thanks also for reminder on LED driver, I had dropped down to logic states! Problem with 74LS latching!

PNP transistor not working 2. Choosing IC with EN signal 2. The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications. Hierarchical block is unconnected 3. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.

Last edited by sharikbaig; 27th August at What is the function of TR1 in this circuit 3. Losses in inductor of a boost converter 9. If you have CD, the remaining 2 gates can be used to combine the 2 switches in one.

Also I may not reply at time. 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. Relay latching in AT89C51 based circuit OE is held tied to ground. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. Turn on power triac – proposed circuit analysis 0. Part and Inventory Search.


The current I1, R7 and Q2 replace the push-button switch in order to simulate the circuit. But when the Latch Enable Pin was pulled low, the data will be latched so that the data appears datadheet providing a Latching action.

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! But when the OE is high the output will be in a high impedance state. How reliable is it?

Distorted Sine output from Transformer 8. Being not a machine, I datzsheet do silly mistakes or miss important things. Notify of all new follow-up comments Notify of new replies to all my comments.

When the OE pin is low input data will appear in the output. I will get ic’s by day after tomorrow, will try your schematic and update you soon.
