Re: I/O circuits design
hai,
i am not exactly aware of what u need. anyhow, i came to know in the recent past that 'digital design, principles and practice' by 'john wakerly' is the best book for cmos, ttl etc. but it contains only one or two chapters. i am searching for a e-book of that, but in vain. is that the datasheet that is required for u? then have a look at xxx.ti.com and xxx.analog.com
xxx -> www
that might help u a lot. and i am sure i would give u the links nearly. please bear with me. afterall i am a less than junior level.
arun.
