PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC 7 V Power Dissipation (Note 2) PD 585 mW Output Current (Note 3) IOMAX 1000 mA FG Signal Output IFG 5 mA FG Signal Output Voltage VFG 7 V Operating Temperature TOPR -40~+105 °C Storage Temperature TSTG -55~+150 °C Junction Temperature TJMAX 150 °C Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. To use at temperature above TA=25°C reduce 4.68mW/°C (On 70.00mm×1.6mm glass epoxy board). 3. This value is mot to be over Pd, VCC=4.0V~6.0V At VCC=2.2V~4.0V, output current tolerance reduces.
