here is the question.... could we build the DRIVEN interface using SMD components?

i know the moral to the story is K.I.S.S. (keep it simple stupid) but it would be nice to SHRINK the interface to a concealable size...

would the tolerances and voltage change?

capacitors 0.1µF http://www.newark.com/taiyo-yuden/lmk105bj104kv-f/ceramic-multilayer-capacitor/dp/86H5618

resistors 4.7k ohm http://www.newark.com/jsp/search/productdetail.jsp?sku=59M5086&_requestid=156900

MAX232ACPE+ http://www.newark.com/maxim-integrated-products/max232acpe/transceiver-ic/dp/68K4544

i also saw these http://www.newark.com/jsp/search/browse.jsp?N=500003+1001967+294105+283589+252745+2996x91+462530&Ntk=gensearch_001&Ntt=categorynumber85895&Ntx=&getResults=true&appliedparametrics=true&locale=en_US&originalQueryURL=http%3A%2F%2Fwww.newark.com%2Fjsp%2Fsearch%2Fbrowse.jsp%3FN%3D500003%2B1001967%26Ntk%3Dgensearch_001%26Ntt%3Dcategorynumber85895%26Ntx%3D%26getResults%3Dtrue%26appliedparametrics%3Dtrue%26locale%3Den_US
they are smd 232 chips would any of these work? or stick to the hybrid setup?

ZENER DIODE http://www.newark.com/jsp/search/productdetail.jsp?sku=01P3368&_requestid=158632 would these zeners work?

could the power source be 3 1.5v button cells? or a 4.5v car remote battery

see i want to make a circuit with the IC on top ant a small drawn circuit with the SMD's on the opposite side... so the footprint would be no bigger than the IC, just slightly thicker

think of a thumb drive with a DB9 connector....

cost of the components is not the issue @ less than $10 USD... more of do i have the proper components... in theory it should be the same right?

or the whole thing could be contained in the 4th slot in a battery compartment

Perfect, but I am not sure what is the problem or how can we help you?
Oh, button cells too? Come on! Wink

the question or problem is ....

which ic or does it matter? and has anyone else done this

using alternate power sources not recommended?

having issues picking out the right zener diode in a SMD
