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
Video cassette recorders and televisions
•
Features
1) Three 2-input / 1-output switches.
2) 5V power supply.
3) Pedestal clamp inputs
4) Low power consumption (62.5mW Typ.).
5) Excellent frequency characteristics
(10MHz, – 1dB Typ.).
6) Wide dynamic range (2.6Vp-p Typ.).
7) Fast switching speed (50ns Typ.).
