Chips

Archiver

Could someone tell me how I should go about learning what other chips are
out there and what their requirements/capabilities are?
I am looking for a cheap chip that can do serial and TTL communications. I
was thinking a PIC chip could do this but I don’t know where to look for
more information.



Thanks,

Hi Wayne,

I am glad your dart communications work now.
You keep misunderstanding the difference between serial communication ,which
is defined by a protocol,
and TTL, which is an electronic speification, defined by voltages, fan-in,
fan-out, etc.
To learn more about basic TTL devices and their functions try a seach engine
and look for
74LS or 74HCT or 74HC. These are all prefixes for the popular 74 series TTL
devices. Many of their functions
are also available in the CMOS 4000 series, which is another electronic
specification.
You can start at http://www.cs.uiowa.edu/~jones/logicsim/man/node5.html
or http://store.yahoo.com/webtronics/74ls-family.html
Remember: all 74LS devices are also available as 74HC devices which consume
less power and usually have better
response tiiming (i.e work on higher frequencies).
Info about PIC can be obtained from http://www.microchip.com
