When the pulse width is 50ns or less, the Min value of Input Voltage/Output Voltage is not lower than -1.0V. Tjmax 150 °C Junction temperature at the storage condition VESD -4000 to +4000 V Input Voltage / Output Voltage Junction Temperature Electrostatic discharge voltage (human body model) Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
