R5 and R8 set a small bias level to reduce the otherwise quite wide neutral deadband caused by the forward voltage drops of the 1n4148's.
R5的和r8设置一个小的偏见水平，以减少，否则相当广泛中立的死所带来的正向电压下降的1n4148的。
During an ESD event, both D1 and D2 can conduct, but the voltage at VIN exceeds the power-supply-rail voltage by only two forward-biased diode voltage drops.
在ESD事件中，D1和D2可以进行传导，但通过两个前置偏移二极管压降，VIN端的电压超出供电电源电压。
