Electrical Characteristics (Cont.)
Note 2.Tlow=0°CV, high=+70°C 3.Low duty cycle pulse techniques used during test maintain junction temperature close ambient temperature possible. 4.If output switch driven into hard saturation (non-Darlington configuration) switch currents (300mA) high driver currents (30mA), take 2.0µs come saturation. This condition will shorten time frequencies30kHz, magnified high temperatures. This condition does occur with Darlington configuration, since output switch cannot saturate. non-Darlington configuration used, following output drive condition recommended output Forced output switch driver 7.0mA* resistor emitter driver device requires about 7.0mA before output switch conducts.
