Overview
Multimedia ICs 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.
).
