Video signal switcher
BA7606 / BA7606F
The BA7606 and BA7606F are switching ICs developed for use in video cameras. Each contains three two-channelanalog multiplexers. They feature a large dynamic range, and wide operating freqency range, and the switches
have pedestal clamp inputs which are ideal for switching RGB and video signals.
•
Applications
