how does the IC CD4093 work?

Question

i have made a project called MICRO-POWER FLASHER.In this project i have used IC CD4093,but i don't know how the IC work.

Answer 1

You can get more information on this National integrated circuit at the link below.

Answer 2

The 4000 series CMOS chips were made by a number of companies, not just National Semiconductor. For example, I have attached the datasheet from Fairchild below and these chips can still be purchased at Digi-Key from manufacturers Texas Instruments and Fairchild. I thought they were phasing out production of 4000 series CMOS and that it shouldn't be used in new designs, but apparently it is still available.

The CD4093 is a quad NAND gate with Schmidt triggers on each input. This will have the NAND logic function (Not AND) with a truth table:

A and B are inputs, Y is the output
A__B__Y
0__0__1
0__1__1
1__0__1
1__1__0

The Schmidt trigger on the inputs causes the inputs to have a hysterisis which is good for rejecting noise on the inputs or for slowly transitioning inputs. It sets a higher threshold for a rising signal and a lower threshold for a falling signal level before that input is considered high or low.

I am... bucolic, fairly dogmatic, pragmatic, dramatic, animalistic, realistic, apologetic, fantastic (maybe), linguistic and moronic!
