No.11066EAT02
●Description
These video switching ICs, which contain two or three 2-input circuits, were developed for switching TV, DVD, and other
video signals. Input pin formats can be selected from bias mode (R=20 kΩ), sync-tip mode, and pedestal clamp mode.
Having a large dynamic range and broad frequency characteristics, these switches are suited to a wide range of applications
from audio signals to video signals.
●Features
1) Contain three 2-input, 1-output switch circuits
2) Power supply voltage (4.5~5.5 V)
3) Low power consumption
4) Good frequency characteristics
5) Large dynamic range
6) Bias input (BA7602F)
Sync-tip clamp input (BA7603F)
Pedestal clamp input (BA7606F, BA7606FS)
Bias input + sync-tip clamp input (BA7607F, BA7609F, BA7627FV)
7) Large input impedance (Typ.20kΩ)
8) Fast switching speed (Typ. 50ns)
●Applications
For switching TV, DVD, and Other video signals
