When using at Ta=25C or higher 3.3mW to be reduced per 1C. 0.33 (TSSOP-B8) Storage Temperature Tstg - 65 to +150 C Operating Temperature Topr - 40 to +85 C The Max value of Terminal Voltage is not over 6.5V. Input Voltage / When the pulse width is 50ns or less, the Min value of Terminal - 0.3 to Vcc+1.0 V Output Voltage Voltage is not under -1.0V. Junction temperature at the storage condition Junction temperature Tjmax 150 C Electrostatic discharge voltage VESD -4000 to +4000 V (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.
