We noticed that many new machines have a delayed start option which would be very useful because it would be possible to fill the machine and datsheet it and it would start working 74ls1162 itself during cheaper time. PDF generated using the open source mwlib toolkit.

Help me to find this datasheet 74ls12 download. The outputs go to the buttons and one is paralleled with the dryer start switch as you mentioned.

They are edge-triggered, synchronously presettable, and cascadable MSIbuilding blocks for counting, memory addressing,frequency division and otherapplications. There are problems with timer datasheer. This planar stripe MOSFET has better characteristics, such as fast switching time, low on resistance, low gate charge and excellent avalanche characteristics. It looks promising to me. Then use a counter using the 1Hz pulses as clk and use it to count the seconds. In general I have found that using a “complex” circuit of discrete components is usually 74ls12 with minor errors in both design and construction that cause them to take a lot of time and money.

Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. Yah, I know, it’s kinda funny. Doing a timer like this is very easy to do on a very cheap micro since you don’t need it to do anything special.

74LS162 (16PIN)

Logic Families – Wikimedia Commons ; Aug 11, Have it send you an SMS? One of my friends needs a new laundry washing machine, so I went browsing with her. As for the oscillator, the slowest crystal I could find is 32 KHz which is too fast for me. I’ll take a look. At least dagasheet will work in the presence of a Tesla coil while being tapped by a hammer or the washer’s spin cycle.

I don’t think that it would be too complicated to make a circuit which will start a washing machine after X amount of time.


I’m thinking that the button could be replaced by a transistor or some sort of normally off relay. Fri Sep 25, 8: I thought about using capacitor and coil to make my own oscillator. Confirm that you have. The simplest and most pre-fabricated solution. Because of that, many people tend to turn on big energy consumers after midnight, when electricity is cheaper.

I didn’t think too much about power supply, but I’d either use “wall-wart” adapter or check the insides of the washing machine for any available power sources. Post as a guest Name. Actually the Chip itself can drift with temperature.

74LS Datasheet PDF ( Pinout ) – Synchronous Decade Counters(synchronous clear)

It is a free download and can be used as a layout In 74LS’s datasheet under minimum frequency it says 25MHz if I’m reading it right, so I guess that it doesn’t fit my needs, but 74LS has 0 as minimal frequency so it looks like a logical choice to me. Sign up or log in Sign up using Google. List of series integrated circuits – Wikipedia ; The following is a list of series digital logic integrated circuits.


It was interesting to program with ladder logic too.

General directions for a timer circuit which will not use microcontroller and which can measure several hours needed Ask Question.

The resistors and capacitors use to set the frequency are not all that accurate, and they drift with temperature. In my country, price of electricity depends among other things on the time of the day when energy is used.

I know that a microcontroller is the most elegant solution, but I’d rather skip collecting necessary gear for working with them at this time. Master Selection tilde – Description ; In the event of conflict with this selection guide, the data sheet specifications shall Home Questions Tags Users Unanswered. I’ll take it into consideration.

JeffV 1 5 Plug your devices and an AC relay rated for your countries power into it. Hitachi bears no responsibility for failure or damage when used. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.

Will be grateful daatsheet any help! My first idea is to create or find prefabricated some sort of counter which would datashet connected to a slow oscillator. Some TTL logic parts were made with an extended military- specification Mount it straight into the control panel plate of the washing machine Thank you very much.
