hi you all,
i was woundering,
if i am using an I2C bus of 400khz speed does it meens that i am transfaring data in 25kbps??
coz,
if i anderstand rigth transfaring at the clk rate of 400khz per bit,
but i have to sent the 7 bit adress +1 bit rd/wr and then i get my 8 bit data so in order to...
Re: Layout Orcad
i know i can make one on myohwn but,

if anybady has the falowing:
1) 10 lead MSOP footprint.
2)SSOP footprint.
3)SOP footprint.
4)LCD footprint.
5) keyborad footprint.
6) TSOP footprint.
and so on......
thank's alot .....
