Overview
The LA7951 Video Switch is a solid-state 4-input 4-output
video switch ideally suited for use as a video selector switch
in multiple-source video systems and multiple VCR video
editing systems.
The Switching logic, coupled with built-in video ampli-
fier, ripple filter and 75
Ω output driver facilitate a mini-
mum parts count video switching subsystem. The solid-
state switches feature low crosstalk and wide bandwidth.
The LA7951 operates from a single 12V power supply, and
is available in 14-pin plastic DIPs.
