2. FDS9435A Single P-Channel Enhancement Mode Field Effect Transistor
SO-8 P-Channel enhancement mode power field effect transistors are produced using
Fairchild's proprietary, high cell density, DMOS technology. This very high density process is
especially tailored to minimize on-state resistance and provide superior switching
performance. These devices are particularly suited for low voltage applications such as
notebook computer power management and other battery powered circuits where fast
switching, low in-line power loss, and resistance to transients are needed.
·Features
-5.3 A, -30 V, RDS(ON) = 0.045 Ω@ VGS = -10 V,
RDS(ON) = 0.075 Ω@ VGS = - 4.5 V.
High density cell design for extremely low RDS(ON).
High power and current handling capability in a widely used surface mount package.

3. FLI8125
The FLI8125 is a cost-effective, highly-integrated, mixed signal solution for TV and Digital
Video applications. It incorporates a multi-standard video decoder, high-speed triple 8-bit
Analog-to-Digital Converter(ADC),and front end switching. An integrated VBI Slicer adds
Closed Captioning(CC) and Teletext service support, and the built-in microprocessor enables
full system control without external devices.
