My project I would like to use LSF0108 level converter for SPI,I2C,UART ,GPIO pin interfacing with various 5v external module to 3.3V TM4C1294 controller .My doubt is when i need to add pull up resistor?? .
This lines are confused me when i am reading datasheets .
"If either output is push-pull, data must be unidirectional or the outputs must be tri-state and be controlled by some direction-control mechanism to prevent HIGH-to-LOW bus contention in either direction. If both outputs are open-drain, no direction control is needed".
kindly give some explanation to my understand.
Thanks in advance.
