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 amplifier, ripple filter and 75Ω output driver facilitate a minimum parts count video switching subsystem. The solidstate switches feature low crosstalk and wide bandwidth.
The LA7951 operates from a single 12V power supply , and
is available in 14-pin plastic DIPs.
Features
• 4-input 4-output multi-functional video switch.
• Low crosstalk, wide bandwidth.
• Internal 6 dB video amplifier.
• Ripple filter.
• 75Ω output driver for video monitor (COMMON OUT).
