BA7606F

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.).
