Level shifting hot swappable I2C-bus and SMBus bus buffer

8.11 Additional system compromises

• Additional parts

• Additional assembly cost

• Reduced system reliability due to complexity

• Reduced logic level noise margin (immunity)

• Sensitivity to ground offsets between sub-systems (cable links, for example)

• Increased loading on the low voltage side (must carry the high voltage side

sink current)

• ESD robustness
