Input Voltage / When the pulse width is 50ns or less, the Min value of Input -0.3 to Vcc+1.0 V Output Voltage voltage/Output voltage is not lower than -1.0V. Junction Tjmax 150 C Junction temperature at the storage condition Temperature Electrostatic Discharge Voltage V -4000 to +4000 V ESD (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.
