Re: [lpc2000] Alternative Circuit

2004-12-11 by onestone

Sipex, maxim, Ti, On Semi, to name just 4, all supply RS232 drivers in 
3V versions. So I don't understand the problem, since All of these (I 
think) have a direct sales facility over the net. Even if you don't have 
a distributor you should be able to buy them. Failing the above 
Digi-key, Jameco RS and farnell/Newark all sell them and will ship anywhere.
