SCART Video Switching
The DG894 is a monolithic video selector designed for
switching a variety of component video signals. The low
on-resistance and low capacitance of the DG894 make it ideal
for video/audio signal routing. Switch control can be through
direct CMOS addressing or through the two-wire I
2
C bus.
The DG894 is built on the Vishay Siliconix proprietary
D/CMOS process that combines n-channel DMOS switching
FETs with low-power CMOS control logic and drivers.
Low-capacitance DMOS FETs are used to achieve high levels
of off isolation at low cost.
