hi,
we are designing a GPIB interface board using NAT9914,the MCU is stm32F103VE,3.3V voltage power suply,and the NAT9914 is a 5V chip,so my question is should I connect external pull-up resistors to these adress bus(RS0~RS2),and also CE,WE,DBIN,or just directly connect the IO of STM32 to these pins?thank you!
