Note: HBM all pins pass 3KV except High Voltage Input pin. The details are VIN passes 1kV, VDD passes 1.5KV, all other I/Os pass 3KV. In

system application, High Voltage Input pin is either a high impedance input or connected to a cap. The lower rating has minim um impacts on

system ESD performance.
