Hi, I'm reletively familiar with electronics, and I'm trying to find
some information regarding implementing logic into a circuit I want to
build.
I am having trouble however actually learning how to actually USE an
AND gate. The IC I am using is: 74LS08, a data sheet can be found at:
http://pdf.alldatasheet.com/datasheet-pdf/view/12619/ONSEMI/74LS08.html
It is a simple QUAD 2 Input AND Gate. However, when I try to use it, I
am unable to make it work correctly. I am trying to use anywhere
between 6-9Vdc. The circuit I use basically has two switches, one LED,
and the IC. I have the IC hooked up to a positive and ground/negative
of my power supply, and each switch is hooked up to pins 2 and 3 on the
IC (the input gates of the logic switch), and they are hooked up on the
other side to a positive voltage. The LED is connected to the output of
the AND Gate. When both switches are on, the circuit is closed and the
light is on, however when one switch is off, the light still stays on.
is there anything i am doing wrong? or does anyone have some websites
that might help me? I have been googling this for a while but have had
no luck.
thank's
