AN5870K
Wide bandwidth analog switch IC
s
Overview
The AN5870K is a wide bandwidth analog switch IC
of 300 MHz operation. It is usable for RGB signal and
horizontal/vertical synchronizing signals, and it has a
built-in 75
driver for video signal. In addition, it has
also realized a high speed operation by the adoption of
CMOS process for its sync. signal processing circuit. It is
usable in a broad range from a popular type monitor to a
high definition monitor.
