Power supply and low/high-level voltage
November 27, 2011
I am trying to have these two components work together:
The electrical specs are the following:
Input Low/High: 0.3VDD / 0.7VDD
Output Low/High with VDD@1.8V: 0.25VDD / 0.7VDD
Output Low/High with VDD@3V: 0.05VDD / 0.9VDD
Input Low/High: 0.45V / 0.7VDD (max 3.6V)
Output Low/High: 0.4V / 0.75VDD
My question is quite simple. In your opinion, what would be the best way to have these work correctly together (power supply + logic levels)? This system will run on a little lithium battery, and my main requirement is to minimize the power consumption as much as possible. I would be grateful if you could give me your input on this.
Thanks a lot in advance for your help!
