Designed specifically for high-speed/high-density optical media applications, the FAN8741/FAN8742’s power stage is created by D-MOS transistors which have extremely low RDSON. This enables less heat generation and guarantees improved reliability. The FAN8741G/FAN8742G is available in a 56-SSOP-HS pack- age, which has high-power dissipation and the leadframe is exposed to the top side. The FAN8741MTF/FAN8742MTF is available in a 56-TSSOP-EP package, which is very thin and the leadframe is exposed to the bottom side. Ordering Information HS=HeatSlug, EP=ExposedPad X:Tape & Reel type FAN8741:FG3X FAN8742:FG1X Device Package Operating Temp.
