hellokitty9999 WROTE:Hi allen, if i use one voltage regulator, what logic chips should i use??
Thank you.
If only 3.3V is available, then you have to use Low Voltage Logic chips like
Fairchild low voltage logic, Fairchild Semiconductor - Global Leader in Power Optimization

3.3V Logic - STMicroelectronics
