... VCC - 0.3V, activating the fail-safe circuit and forcing the outputs high (Figure 1). Overshoot and Undershoot Voltage The MAX9174/MAX9175 are designed to protect the power-down inputs (PD0 and PD1) against latchup due to transient overshoot and undershoot voltage. If the input voltage goes above VCC or below GND 1V, an internal circuit limits input current to 1 ...

... The IEC 61000-4-2 model specifies a 150pF capacitor that is discharged Board Layout into the device through a 330Ω resistor. The MAX9174/ MAX9175 differential inputs and outputs are rated for IEC 61000-4-2 level 4 (±8kV Contact Discharge and ±15kV Air-Gap Discharge). The Human Body Model (HBM, Figure 10) specifies a 100pF capacitor that is discharged into the device through a 1.5kΩ ...
