Subject: Low power logic design

Can anybody help I am designing a very low powered circuit using a simple CMOS logic circuit interface to a series of SPST switches. I need to keep the current consumption very low for battery applications. Please can anyone advise as to what the maximum value of pull up resistor I can use for a switch input is. The logic gates will probably be 4000 series or even Arizona Microchip PIC16C711 microcontrollers.> > Cheers > > Nigel
