You could try using a ground strap thin copper braid around your datashdet and ground to the IC’s ground to avoid static damage. Sign up using Facebook. I assume that the memory enable should just stay low at all times, but I did try moving it around. It is my first time using this.
I see that for the question on how big a pull-up resistor in general should be. Rather than just moving wires to change your inputs, it would be well worth your while to get a DIP switch and a bunch of resistors or a SIP resistor network. This is a follow up question to this question. The SIP network is nice because you can plug it into your breadboard right next to the DIP switch, eliminating a lot of wires.
So now I have the following schematics more or less copied from here.
I would hook 789 up as follows:. Do I need some resistors somewhere in all of this? For example, in the answer to the earlier question, the resistors R1, R2, R3, and R4, were suggested to be 2. WE state – and if they’re high they shouldn’t be able to light the LEDs.
I need to check the sink current for this IC.
Please look at the “Related” column to the right and click on “How do I calculate datasjeet required value for a pull-up resistor?
Lower current gives less light, but for indicator light use I find tha 10 mA is more than enough, so I’d use Ohms or more. Low impedance also protects against accidental signal pickup stray capacitance, datqsheet discharge.
That is what I was thinking. For LED drive, you do the same thing: What should I be looking for in the datasheet? Thanks for the answer. A resistor obeys Ohm’s law, and choosing a resistor value is a matter of the permissible voltage and current, and power voltage drop x current according to application. I still can’t get it to work, but I will accept your answer because you provide a general schematics for the chip.
Have I understood this correctly? If it is only the LEDs forward voltage 2V and current 0. If the IC’s output is irrational then it is oscillating or it is blown.
