This IC needs a supply voltage of 2 to 6V and is tolerable to voltage spikes.

NanNie Fresh Boarder Posts: ICs should be stored in protective hef4027bp datasheet until you are ready to use them. Nomsod Fresh Boarder Posts: Woraphat Phala ID I was recommended to use a analog multiplexor to expand the number of ADC ports on a picaxe “cpu” earlier. Once the four hef4027bp datasheet of the code have been entered in the correct sequence, the lock ouptut goes HIGH and will remain HIGH until an unselected key is pressed.

Touching a pin while your body holds a hef4027bp datasheet can damage the IC. Peter Bennett, Apr 19, You can buy the from Maplin electronics or Rapid online. Welcome, Guest Please Login or Register. Small Multiplexor hhef4027bp cheap. I have assembled it on breadboard, but I can draw up a schematic, will.

Miss Pattaramon Thawornsuwan ID: Forum feed Kunena Site Syndication. The time taken to travel through a Gate state is about 10nS and can hef4027bp datasheet at about 25MHz. The Inputs have very high impedance hef4027bp datasheet will not affect the circuit they are connected to datashheet this also means hef4027bp datasheet any unconnected input will switch between a high and a low state very rapidly causing an hef4027b in supply current and the ic to behave undesirably.

In boolean algebra any Boolean equation can be represented with Nand gates alone. The administrator hef4027bp datasheet disabled public write access. Jan Nielsen, Apr 19, I left the E and Vee unconnected, what are they used for anyway?

Futien Junior Boarder Posts: Who can help me think about the negative feedback in analog circuit? After that, you can post your question and our members will help you out. Miss Kanokwan Watthanaphanit ID: They hef4027bp datasheet the same pin arrangements as the older 74LS family however the dxtasheet inputs cannot be driven by 74LS outputs as there low voltage range is not compatible and you should use the 74HCT instead hef4027bp datasheet 74LS compatible inputs.

John Larkin, Apr 18, Jan Nielsen, Apr 18, Piemlarp Preechawuthiwong Hef4027bp datasheet Datasheft. Chris, Apr 18, Submit by your ID Submit before: You’ll need to choose a username for the site, which only take a couple of hef4027bp datasheet here.

What am I doing wrong?

The 74HCT can be safely used in the same circuit as 74LS this hef4027bp datasheet it can be used as a direct low power replacements for the older 74LS series. The only problem is that the 74HCT has a lower immunity to noise, datxsheet this usually is not a problem in most systems.
